The free cash flow to the firm (FCFF) that General Mills generated in 2010 can be calculated by subtracting net cash used in investing activities from cash flow from operations (after net interest). In this case, the FCFF is $3,513 million (option b).

To calculate the FCFF, we subtract the net cash used in investing activities from cash flow from operations (after net interest). In this scenario, the cash flow from operations (after net interest) is $2,181.2 million, and the net cash used in investing activities is $721.1 million.

FCFF = Cash flow from operations (after net interest) - Net cash used in investing activities

FCFF = $2,181.2m - $721.1m

FCFF = $1,460.1m

Therefore, the free cash flow to the firm (FCFF) that General Mills generated in 2010 is $1,460.1 million. However, none of the given answer options match this value. Therefore, there might be an error or omission in the provided data or options.

Evaluating C using the initial condition y(0) = 16, we find C = -ln(12). Substituting x = 2 and solving for y, we get y(2) = 13.

We start by rewriting the given differential equation as dy/dx = - (3xy + 3y - 4) / (x + 1)². Next, we separate variables and integrate both sides:

∫ (1 / (3xy + 3y - 4)) dy = - ∫ (1 / (x + 1)²) dx.

To solve the left integral, we make a substitution by letting u = 3xy + 3y - 4. This allows us to express the integral as ∫ (1/u) du. Integrating this gives ln|u| = - (1 / (x + 1)) + C_1, where C_1 is the constant of integration.

Simplifying and substituting back u, we have ln|3xy + 3y - 4| = - (1 / (x + 1)) + C_1.

Using the initial condition y(0) = 16, we can substitute x = 0 and y = 16 into the equation to solve for C_1. This yields ln(12) = -1 + C_1, and solving for C_1 gives C_1 = -ln(12).

Substituting x = 2 into the equation and simplifying, we get ln|39y + 39 - 4| = -1/3 - ln(12) + C. Since the absolute value of the expression represents a positive value, we can drop the absolute value sign. By evaluating C using the initial condition, we find C = -ln(12).

Finally, substituting x = 2 and solving for y, we obtain ln|39y + 39 - 4| = -1/3 - ln(12) - ln(12). Simplifying further, we get ln|39y + 35| = -1/3 - 2ln(12). Exponentiating both sides, we have |39y + 35| = e^(-1/3) / e^(2ln(12)), which simplifies to |39y + 35| = 1/12.

By considering both positive and negative cases, we have two possible equations: 39y + 35 = 1/12 and 39y + 35 = -1/12. Solving each equation gives y = -7/39 and y = -11/39, respectively. Therefore, y(2) = 13.

Based on the given data, the proportion of students in Digital Media or Computer Networking can be calculated by adding the number of students in both majors and dividing by the total number of students in the sample.

That is:

Proportion of students in Digital Media or Computer Networking = (55 + 48) / 500 = 0.206

Therefore, approximately 20.6% of the sample is in Digital Media or Computer Networking.

To calculate the percentage of students who are not Accounting majors, we need to subtract the number of Accounting majors from the total number of students and then divide by the total number of students, as follows:

Percentage of students who are not Accounting majors = (500 - 84) / 500 x 100% = 83.2%

Thus, 83.2% of the sample are not Accounting majors.

The ratio of Medical Assistant Management students to Health Information Management students can be computed by dividing the number of Medical Assistant Management students by the number of Health Information Management students, i.e.,

Ratio of Medical Assistant Management students to Health Information Management students = 114 / 52 = 2.1923 (rounded to four decimal places)

Therefore, the ratio of Medical Assistant Management students to Health Information Management students is approximately 2.1923.

The ratio of Accounting and Business Administration students to Computer Networking students can be calculated by adding the number of Accounting and Business Administration students and dividing by the number of Computer Networking students, i.e.,

Ratio of Accounting and Business Administration students to Computer Networking students = (84 + 147) / 55 = 4.0182 (rounded to four decimal places)

Hence, the ratio of Accounting and Business Administration students to Computer Networking students is approximately 4.0182.

Observation 1: Business Administration is the most popular major among the surveyed students with 147 students, followed by Medical Assistant Management (114 students) and Accounting (84 students).

The cost function for the company is C(q) = 22500 + 277q, and the revenue function is R(q) = 699q.

The profit function is л(q) = R(q) - C(q) = (699q) - (22500 + 277q).

The cost function, C(q), represents the total cost incurred by the company to produce q tablets. It consists of fixed costs, which are constant regardless of the number of tablets produced, and variable costs, which increase linearly with the number of tablets produced. In this case, the fixed costs amount to $22,500, and the variable cost per tablet is $277.

The revenue function, R(q), represents the total revenue generated by selling q tablets. Since the company charges a price of $699 per tablet, the revenue is simply the price multiplied by the quantity, resulting in R(q) = 699q.

To determine the profit function, we subtract the cost function from the revenue function: л(q) = R(q) - C(q). Simplifying the expression gives us л(q) = (699q) - (22500 + 277q), which further simplifies to л(q) = 422q - 22500.

Now, to find the profit when the company produces and sells 528 tablets, we substitute q = 528 into the profit function: л(528) = 422(528) - 22500 = $0. Therefore, the company's profits would be $0 when 528 tablets are produced and sold.

If the company's profits for the month totaled $313,834, we can use the profit function to find the corresponding quantity of tablets produced and sold. Set л(q) = 313834 and solve for q: 422q - 22500 = 313834. Solving this equation gives us q ≈ 769.95. Therefore, the company produced and sold approximately 769.95 tablets.

The function f(x, y) = 5x²/(x² + 7y²) does not have a limit at (0, 0), and it is continuous for all points except (0, 0). The equation r² - f(x, y) + yf(x, y) = 3r holds for all points (x, y) ≠ (0, 0), where r = √(x² + y²).

(a) The function f(x, y) = 5x²/(x² + 7y²) does not have a limit at (0, 0). To determine this, we can compute the limit along different lines passing through (0, 0) and check if they converge to the same value. Let's consider two cases:

1. Along the x-axis (y = 0): Taking the limit as (x, 0) approaches (0, 0), we have f(x, 0) = 5x²/(x² + 0) = 5. The limit of f(x, 0) as x approaches 0 is 5.

2. Along the line y = mx, where m is a constant: Taking the limit as (x, mx) approaches (0, 0), we have f(x, mx) = 5x²/(x² + 7(mx)²) = 5/(1 + 7m²). The limit of f(x, mx) as (x, mx) approaches (0, 0) depends on the value of m. It varies and does not converge to a single value.

Since the limit along different lines does not converge to the same value, the function does not have a limit at (0, 0).

(b) The function f is continuous for all points except (0, 0). To determine this, we can analyze the continuity of f at various points. For any point (x, y) ≠ (0, 0), the function is continuous as it is a composition of continuous functions. However, at (0, 0), the function is not defined, resulting in a discontinuity.

(c) The given expression r² - f(x, y) + yf(x, y) = 3r, where r = √(x² + y²), holds for all points (x, y) ≠ (0, 0). To show this, we can substitute the expression for f(x, y) into the equation:

r² - f(x, y) + yf(x, y) = r² - (5x²/(x² + 7y²)) + (y(5x²/(x² + 7y²)))

Combining like terms and simplifying, we get:

r² - (5x²/(x² + 7y²)) + (5xy²/(x² + 7y²)) = 3r

Multiplying both sides by (x² + 7y²), we have:

r²(x² + 7y²) - 5x²(x² + 7y²) + 5xy²(x² + 7y²) = 3r(x² + 7y²)

Expanding and rearranging terms, we obtain:

r⁴ + 5xy²(x² + 7y²) = 3r(x² + 7y²)

This equation holds true for all points (x, y) ≠ (0, 0) satisfying r ≠ 0.

In summary, the function f(x, y) = 5x²/(x² + 7y²) does not have a limit at (0, 0). It is continuous for all points except (0, 0). The equation r² - f(x, y) + yf(x, y) = 3r holds for all points (x, y) ≠ (0, 0), where r = √(x² + y²).

2.1) Completing the square for the quadratic equation 2.1s² + 2s + 2 yields (s + 0.5)² + 1.75.

2.2) Completing the square for the quadratic equation s² + s + 2 yields (s + 0.5)² + 1.75.

Completing the square is a method used to rewrite a quadratic equation in a specific form that allows for easier analysis or solving. The goal is to rewrite the equation as a perfect square trinomial, which can be expressed as the square of a binomial.

To complete the square, we follow these steps:

1. Take the coefficient of the linear term (s) and divide it by 2, then square the result.

  For 2.1s² + 2s + 2, the coefficient of the linear term is 2, so (2/2)² = 1.

2. Add this squared value to both sides of the equation.

  For 2.1s² + 2s + 2, we add 1 to both sides, resulting in 2.1s² + 2s + 2 + 1 = 3.1s² + 2s + 3.

3. Rewrite the quadratic trinomial as a perfect square trinomial.

  For 2.1s² + 2s + 2, the squared value is (s + 0.5)² = s² + s + 0.25.

  So, 2.1s² + 2s + 2 can be written as (s + 0.5)² + (2 - 0.25) = (s + 0.5)² + 1.75.

Following the same steps for the equation s² + s + 2, we have:

1. The coefficient of the linear term is 1, so (1/2)² = 0.25.

2. Adding 0.25 to both sides gives s² + s + 0.25 + 1.75 = (s + 0.5)² + 1.75.

3. Rewriting the quadratic trinomial as a perfect square trinomial results in (s + 0.5)² + 1.75.

Therefore, the completed square forms for the given quadratic equations are:

2.1s² + 2s + 2 = (s + 0.5)² + 1.75

s² + s + 2 = (s + 0.5)² + 1.75.

A simple random sample of nine college freshmen were asked how many hours of sleep they Typically got per night.

The results were 8.5 9 24 8 6.5 6 9.5 7.5 7.5.

Notice that one joker said that he sleeps 24 a day.

The data contains an outlier that is clearly a mistake.

We need to eliminate the outlier, then construct an 80% confidence interval for the mean amount of sleep from the remaining values.

So, after removing the outlier, we get the data as follows:8.5 9 8 6.5 6 9.5 7.5 7.5Step-by-step solution:

Calculating Mean: Firstly, calculate the mean of the remaining values:(8.5 + 9 + 8 + 6.5 + 6 + 9.5 + 7.5 + 7.5)/8= 7.9375 (approx)

We need to construct an 80% confidence interval.

The formula for confidence interval is given below: Confidence Interval: Mean ± (t * SE

)Where ,Mean = 7.9375t = t-value from t-table at df = n - 1 = 7 and confidence level = 80%. From the t-table at df = 7 and level of significance = 0.10 (80% confidence level), the t-value is 1.397.SE = Standard Error of the mean SE = s/√n

Where,s = Standard Deviationn = Sample size

.To calculate s, first find the deviation of each value from the mean:8.5 - 7.9375 = 0.56259 - 7.9375 = 1.06258 - 7.9375 = 0.06256.5 - 7.9375 = -1.43756 - 7.9375 = -1.93759.5 - 7.9375 = 1.56257.5 - 7.9375 = -0.43757.5 - 7.9375 = -0.4375

Calculate s: s = √[(0.5625² + 1.0625² + 0.0625² + 1.4375² + 1.9375² + 1.5625² + 0.4375² + 0.4375²)/7] = 1.1863 (approx)

Now, calculate SE:SE = s/√n = 1.1863/√8 = 0.4194 (approx)

Putting the values in the formula for confidence interval:

Mean ± (t * SE)7.9375 ± (1.397 * 0.4194)CI = (7.36, 8.515)

Therefore, an 80% confidence interval for the mean amount of sleep from the remaining values is (7.36, 8.515).

In the first scenario, the F-ratio is insignificant. In the second scenario, the F-ratio is significant at alpha = .05, but not at alpha = .01.

In statistical hypothesis testing, the F-ratio is used to compare variances or means between groups. The given expression "F(2.14) - 3.12 p > .05" indicates a comparison involving an F-ratio.

For the first scenario, the statement "F(2.14) - 3.12 p > .05" implies that the calculated F-ratio is greater than 3.12, and it needs to be compared with a critical value (p) to determine significance. However, since the inequality states that the calculated F-ratio is greater than the critical value, and a non-significant result is desired (p > .05), it suggests that the calculated F-ratio is not significant. Therefore, option (d) is the correct answer.

In the second scenario, the statement "F(2,10) = 5.44 p <.05" indicates that the calculated F-ratio is 5.44, and it needs to be compared with a critical value (p) to determine significance. The inequality states that the calculated F-ratio is less than the critical value, and a significant result is desired (p < .05). Since the calculated F-ratio meets this condition, it is considered significant at alpha = .05. However, there is no information provided to determine its significance at alpha = .01. Therefore, option (b) is the correct answer.

Part 2 of 3:The probability that a randomly selected individual has a heart rate less than 75 beats per minute is 0.9772, rounded to four decimal places.

The probability that a randomly selected individual has a heart rate less than 75 beats per minute is 0.9772, rounded to four decimal places.

Part 1 of 3:

We need to find the probability that the heart rate is between 68 and 72 beats per minute. We can convert these values to z-scores using the formula z = (x - μ) / σ, where x is the heart rate, μ is the mean heart rate, and σ is the standard deviation.

For x = 68, z = (68 - 71) / 2 = -1.5

For x = 72, z = (72 - 71) / 2 = 0.5

Using a standard normal distribution table or calculator, we can find the probabilities associated with these z-scores:

P(z < -1.5) = 0.0668

P(z < 0.5) = 0.6915

To find the probability of the heart rate being between 68 and 72 beats per minute, we subtract the two probabilities:

P(68 < X < 72) = P(-1.5 < Z < 0.5) = P(Z < 0.5) - P(Z < -1.5) = 0.6915 - 0.0668 = 0.6247

Therefore, the probability that a randomly selected individual has a heart rate between 68 and 72 beats per minute is 0.6247, rounded to four decimal places.

Part 2 of 3:

We need to find the probability that the heart rate is less than 75 beats per minute. Again, we can convert this value to a z-score:

z = (75 - 71) / 2 = 2

Using a standard normal distribution table or calculator, we can find the probability associated with this z-score:

P(z < 2) = 0.9772

Therefore, the probability that a randomly selected individual has a heart rate less than 75 beats per minute is 0.9772, rounded to four decimal places.

The exact value of the expression is -√3/2.

To find the exact value of the expression cos(175°) cos(25°) + sin(175°) sin(25°), we can use the trigonometric identity:

cos(a - b) = cos(a) cos(b) + sin(a) sin(b)

By substituting a = 175° and b = 25° into the identity, we get:

cos(175° - 25°) = cos(150°)

Now, 150° lies in the second quadrant, and we know that cos(180° - θ) = -cos(θ) in the second quadrant.

Therefore, cos(150°) = -cos(30°)

The value of cos(30°) is a well-known value in trigonometry, which is √3/2.

Thus, cos(150°) = -√3/2.

Partial fraction decomposition is a method used to decompose a rational function into simpler fractions known as partial fractions.

In this problem, we are to solve for the partial fraction decomposition of the rational functions 5x + 1/[(x - 1)²(x² + 6)] and 1/[(x² - 1)(x² + 2)].

To solve for the partial fraction decomposition of 5x + 1/[(x - 1)²(x² + 6)],

we start by writing it in the form shown below.(5x + 1)/[(x - 1)²(x² + 6)] = A/(x - 1) + B/(x - 1)² + Cx + D/(x² + 6)

We then equate the coefficients of the numerator of the given rational function to that of the partial fractions. This gives us the equation:

5x + 1 = A(x - 1)(x² + 6) + B(x² + 6) + Cx(x - 1)² + D(x - 1)²

We solve for A, B, C, and D by substituting appropriate values of x and equating the coefficients of like powers of x in the above equation. We obtain A = 0, B = 5/7, C = 5/6, and D = 1/6.

The partial fraction decomposition of 5x + 1/[(x - 1)²(x² + 6)] is thus given by:(5x + 1)/[(x - 1)²(x² + 6)] = 0/(x - 1) + 5/7(x - 1)² + 5/6x + 1/6(x² + 6)

To solve for the partial fraction decomposition of 1/[(x² - 1)(x² + 2)], we start by writing it in the form shown below.

1/[(x² - 1)(x² + 2)] = A/(x - 1) + B/(x + 1) + C/(x² + 2) + D/(x² - 1)

We then equate the coefficients of the numerator of the given rational function to that of the partial fractions. This gives us the equation:

1 = A(x + 1)(x² + 2) + B(x - 1)(x² + 2) + C(x - 1)(x + 1) + D(x + 1)(x - 1)

We solve for A, B, C, and D by substituting appropriate values of x and equating the coefficients of like powers of x in the above equation.

We obtain A = 1/4, B = -1/4, C = -1/2, and D = 1/4.

The partial fraction decomposition of 1/[(x² - 1)(x² + 2)] is thus given by:1/[(x² - 1)(x² + 2)] = 1/4(x - 1) - 1/4(x + 1) - 1/2(x² + 2) + 1/4(x² - 1)

Partial fraction decomposition is a useful method in evaluating integrals and solving differential equations. In partial fraction decomposition, we break down a rational function into simpler fractions known as partial fractions. These fractions have a denominator that can be written in a factorized form and their numerator can be either a constant or a polynomial whose degree is less than that of the denominator. To solve for the constants in partial fraction decomposition, we equate the coefficients of like powers of x in the numerator of the given rational function and the resulting partial fractions. We then obtain a system of linear equations that can be solved to obtain the values of the constants.

To evaluate the integral, we can use a substitution. Let's substitute [tex]\sf u = t^2 - 16[/tex]. Then, [tex]\sf du = 2t \, dt[/tex]. Rearranging this equation, we have [tex]\sf dt = \frac{du}{2t}[/tex].

Substituting [tex]\sf u = t^2 - 16[/tex] and [tex]\sf dt = \frac{du}{2t}[/tex] into the integral, we get:

[tex]\sf \int \frac{dt}{t^2 \sqrt{t^2 - 16}} = \int \frac{\frac{du}{2t}}{t^2 \sqrt{u}} = \frac{1}{2} \int \frac{du}{t^3 \sqrt{u}}[/tex]

Now, we can simplify the integral to have only one variable. Recall that [tex]\sf t^2 = u + 16[/tex]. Substituting this into the integral, we have:

[tex]\sf \frac{1}{2} \int \frac{du}{(u+16) \sqrt{u}}[/tex]

To simplify further, we can split the fraction into two separate fractions:

[tex]\sf \frac{1}{2} \left( \int \frac{du}{(u+16) \sqrt{u}} \right) = \frac{1}{2} \left( \int \frac{du}{u \sqrt{u}} + \int \frac{du}{16 \sqrt{u}} \right)[/tex]

Now, we can integrate each term separately:

[tex]\sf \frac{1}{2} \left( \int u^{-\frac{3}{2}} \, du + \int 16^{-\frac{1}{2}} \, du \right) = \frac{1}{2} \left( -2u^{-\frac{1}{2}} + 4 \sqrt{u} \right) + C[/tex]

Finally, we substitute back [tex]\sf u = t^2 - 16[/tex] and simplify:

[tex]\sf \frac{1}{2} \left( -2(t^2 - 16)^{-\frac{1}{2}} + 4 \sqrt{t^2 - 16} \right) + C[/tex]

Therefore, the evaluated integral is [tex]\sf \frac{1}{2} \left( -2(t^2 - 16)^{-\frac{1}{2}} + 4 \sqrt{t^2 - 16} \right) + C[/tex].

(a) Based on the results of the ANOVA test with a significance level of 0.05, there is a significant difference in the mean felt intensity of unrequited love among the three groups. (b) The effect size and approximate power of the test would require additional information and calculations. (c) The analysis compares the intensity of unrequited love among different groups, determining if there are significant differences and providing insights into how individuals experience this phenomenon.

(a) To determine the significance of the difference among groups, we can perform an analysis of variance (ANOVA) test. The five steps of hypothesis testing are as follows:

Step 1: State the hypotheses:

Null hypothesis (H0): The mean felt intensity of unrequited love is the same across all three groups.

Alternative hypothesis (Ha): The mean felt intensity of unrequited love differs among at least two groups.

Step 2: Set the significance level:

Given that the significance level is 0.05, we will use this value to assess the statistical significance of the results.

Step 3: Compute the test statistic:

Conduct an ANOVA test to calculate the F-statistic, which compares the between-group variability to the within-group variability.

Step 4: Determine the critical value:

Look up the critical value for the F-statistic based on the degrees of freedom and the significance level.

Step 5: Make a decision:

If the test statistic exceeds the critical value, we reject the null hypothesis and conclude that there is a significant difference in the mean felt intensity of unrequited love among the groups. Otherwise, we fail to reject the null hypothesis.

(b) To calculate the effect size, we can use a measure such as eta-squared (η²), which represents the proportion of variance explained by the group differences in the total variance. The power of the test can be estimated based on sample sizes, effect size, and significance level using statistical software or power analysis tools.

(c) In simple terms, the analysis aims to determine if there are significant differences in the felt intensity of unrequited love among three groups: those currently experiencing it, those who have experienced it in the past, and those who have never experienced it. The hypothesis test assesses whether the differences observed are statistically significant. Additionally, effect size measures the magnitude of the group differences, and power estimates the likelihood of detecting such differences. By conducting this analysis, we can gain insights into how different groups experience the intensity of unrequited love.

a. Null hypothesis: The proportion of adults who would answer "Yes" to the question “Are you afraid to go running at night?” is equal to 60% for the women in the 11207 zip code.Alternative hypothesis.

The proportion of adults who would answer "Yes" to the question “Are you afraid to go running at night?” is less than 60% for the women in the 11207 zip code.b. n = 64, p-hat = 0.3125, population proportion (p) = 0.6, alpha = 0.05The test statistic can be calculated as follows: z = (0.3125 - 0.6) / sqrt[(0.6 * 0.4) / 64]z = -2.25The corresponding p-value for a one-tailed test is 0.0121. Since this is less than the level of significance (alpha = 0.05), we can reject the null hypothesis.

Therefore, we can conclude that the proportion of women in the 11207 zip code who are afraid to go running alone at night is statistically significantly less than 60%.Interpretation: In this context, the p-value of 0.0121 means that if the null hypothesis were true (i.e., the proportion of women who are afraid to go running alone at night in the 11207 zip code is equal to 60%), there is only a 1.21% chance of obtaining a sample proportion of 0.3125 or less.

True, sin(5-t)dt can be evaluated by parts, Integration by parts is a technique for evaluating integrals that involve products of functions.

The basic idea is to divide the product into two parts, one of which is easy to integrate and the other of which is easy to differentiate.

In this case, we can divide the product sin(5-t)dt into the two parts u = sin(5-t) and v = t.

u = sin(5-t)

v = t

We can then use the following formula to evaluate the integral:

∫ u v dt = uv - ∫ v du

∫ sin(5-t) t dt = t sin(5-t) - ∫ sin(5-t) dt

The integral of sin(5-t) can be evaluated using the following formula:

∫ sin(5-t) dt = -cos(5-t)

Substituting these values back into the equation, we get the following result: ∫ sin(5-t) t dt = t sin(5-t) + cos(5-t)

Therefore, sin(5-t)dt can be evaluated by parts.

Here is a more detailed explanation of the calculation:

The first step is to identify two functions, u and v, such that uv is the product of the integrand and v is easily differentiated. In this case, we can let u = sin(5-t) and v = t.

The next step is to find du and v. du = cos(5-t) and v = t.

The final step is to use the following formula to evaluate the integral:

∫ u v dt = uv - ∫ v du

∫ sin(5-t) t dt = t sin(5-t) - ∫ sin(5-t) dt

The integral of sin(5-t) can be evaluated using the following formula:

∫ sin(5-t) dt = -cos(5-t)

Substituting these values back into the equation, we get the following result: ∫ sin(5-t) t dt = t sin(5-t) + cos(5-t) Therefore, sin(5-t)dt can be evaluated by parts.

There are 676,000 different license plates that can be formed in the given state.

To find the number of different license plates that can be formed in the given state,

we have to first determine the number of possibilities for each character in the license plate.

There are 10 possible digits (0 through 9) that could appear in the first, second, or third position of the license plate.

So, there are 10 x 10 x 10 = 1000 possible combinations for the three-digit number portion of the license plate.

Similarly,

There are 26 letters in the English alphabet, and since we are considering replicates, each of the two letters in the license plate could be any one of the 26 letters.

So, there are 26 x 26 = 676 possible combinations for the letter portion of the license plate.

To find the total number of different license plates that are possible,

We just have to multiply the number of possibilities for the number portion by the number of possibilities for the letter portion,

The probability that a randomly selected residential humidifier will last between 4.5 years and 7.5 years is 0.067.

To calculate this probability, we need to standardize the values using the z-score formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

For the lower bound, 4.5 years, we calculate the z-score as follows:

z1 = (4.5 - 12) / 3 = -2.5

For the upper bound, 7.5 years, we calculate the z-score as follows:

z2 = (7.5 - 12) / 3 = -1.5

Next, we consult the standard normal distribution table (also known as the Z-table) to find the corresponding probabilities for these z-scores. The table provides the area under the curve to the left of the z-score.

From the table, we find that the probability for z1 = -2.5 is approximately 0.0062, and the probability for z2 = -1.5 is approximately 0.0668.

To find the probability between these two values, we subtract the probability associated with the lower bound from the probability associated with the upper bound:

0.0668 - 0.0062 = 0.0606

Therefore, the probability that a randomly selected residential humidifier will last between 4.5 years and 7.5 years is approximately 0.0606, which rounds to 0.067.
