a researcher obtain a statistically significant r=-.91 when n=30. how would you report this?

Answers

Answer 1

A statistically significant negative correlation coefficient of r = -0.91 was obtained from a sample of n = 30. This indicates a strong and significant negative relationship between the variables.

The researcher conducted a correlation analysis and found a correlation coefficient (r) of -0.91, which indicates a strong negative relationship between the variables under investigation. The negative sign indicates that as one variable increases, the other variable tends to decrease, and vice versa.

The statistical significance of the correlation coefficient is crucial in determining whether the observed relationship is likely to be due to chance or if it truly exists in the population. In this case, the report should highlight that the obtained correlation coefficient is statistically significant.

To establish statistical significance, the researcher likely conducted a hypothesis test, such as a t-test or a permutation test, to determine the probability of obtaining a correlation coefficient as extreme as -0.91 under the null hypothesis of no correlation. Since the obtained correlation coefficient is statistically significant, it suggests that the observed negative relationship is unlikely to be a result of chance and provides evidence for a genuine association between the variables in the population from which the sample was drawn.

Reporting this finding is important for conveying the strength and significance of the negative relationship to the readers, providing valuable insights for further analysis and interpretation of the variables under investigation.

Answers

The Binomial 5 - 3c to have a value greater than 80, c must be less than -25.

1. For the binomial 2x - 1 to have a positive value, the expression 2x - 1 needs to be greater than zero. In other words:

2x - 1 > 0.

To solve this inequality, we isolate x by adding 1 to both sides:

2x > 1.

Then, we divide both sides by 2:

x > 1/2.

So, for the binomial 2x - 1 to have a positive value, x must be greater than 1/2.

2. For the binomial 21 - 3y to have a negative value, the expression 21 - 3y needs to be less than zero. In other words:

21 - 3y < 0.

To solve this inequality, we isolate y by subtracting 21 from both sides:

-3y < -21.

Then, we divide both sides by -3, remembering to flip the inequality sign because we are dividing by a negative number:

y > 7.

So, for the binomial 21 - 3y to have a negative value, y must be greater than 7.

3. For the binomial 5 - 3c to have a value greater than 80, the expression 5 - 3c needs to be greater than 80. In other words:

5 - 3c > 80.

part 1 let w be the set of all vectors of the form shown on the right, where b and c are arbitrary. find vectors u and v such that w=span{u, v}. why does this show that w is a subspace of ℝ3?

Answers

The vectors u and v such that w = span{u, v} are u = [1, 0, 0] and v = [0, 1, 0], respectively.

To find vectors u and v such that w = span{u, v}, we need to express the vectors in w in terms of linear combinations of u and v.

Let's consider the vectors in w. We can write a generic vector in w as follows:

w = b × u + c × v

where b and c are arbitrary scalars.

Now, let's choose u = [1, 0, 0] and v = [0, 1, 0].

Substituting these values into the equation for w, we have:

w = b × [1, 0, 0] + c × [0, 1, 0]

= [b, 0, 0] + [0, c, 0]

= [b, c, 0]

So, any vector in w can be expressed as a linear combination of u and v. Therefore, w = span{u, v}.

This shows that w is a subspace of [tex]R^3[/tex] because it can be spanned by a set of two linearly independent vectors (u and v).

A subspace is a vector space that contains the zero vector, is closed under addition and scalar multiplication, and is closed under linear combinations.

In this case, since w can be expressed as a linear combination of u and v, it satisfies the conditions for being a subspace.

The value of the given sine function is √3/2, so the correct option is 2nd.

Given that an function Sin (-5π/3) we need to evaluate the expression,

To evaluate the trigonometric function sine of the angle (-5π/3), we can use the periodicity of the sine function.

Since the sine function has a period of 2, the sine of any given angle is equal to the sine of that angle plus or minus any multiple of 2.

To find an equal angle inside the main range (between -π and π), we can add 2 to the angle (-5/3).

Once adding 2:

(-5π/3) + 2π = (-5π/3) + (6π/3) = π/3

Now we can evaluate the sine of π/3, which is a commonly known angle. The sine of π/3 is √3/2.

Therefore, sin(-5π/3) = sin(π/3) = √3/2.

Hence the correct option is √3/2

To subtract mixed numbers, we first need to convert them into improper fractions and then perform the subtraction.

5 1/4 can be written as an improper fraction:

5 1/4 = (5 × 4 + 1)/4 = 21/4

3 1/8 can be written as an improper fraction:

3 1/8 = (3 × 8 + 1)/8 = 25/8

Now we can subtract these fractions:

5 1/4 - 3 1/8 = 21/4 - 25/8

To subtract these fractions, we need to find a common denominator. The least common multiple of 4 and 8 is 8, so we can rewrite each fraction with a denominator of 8:

21/4 = (21/4) × (2/2) = 42/8

25/8 = 25/8

Now we can subtract the fractions:

5 1/4 - 3 1/8 = 42/8 - 25/8 = 17/8

Therefore, the difference between 5 1/4 and 3 1/8 is 1 7/8.

Answers

The ordered pairs that correspond to input-output pairs for the function are (0, 30) and (10, 70)

To determine which ordered pairs correspond to input-output pairs for the given function

we can substitute the values of t (number of seconds water was added) into the function and check if the result matches the given number of gallons (y).

(50, 5):

Substituting t = 5 into the function:

y = 4(50) + 30 = 200 + 30 =230

The output y is 230, which does not matches the given number of gallons. So, (50, 5) is a not a valid ordered pair.

(0, 30):

Substituting t = 0 into the function:

y = 4(0) + 30 = 0 + 30 = 30

The output y is 30, which matches the given number of gallons. So, (0, 30) is a valid ordered pair.

(3, 37):

Substituting t = 3 into the function:

y = 4(3) + 30 = 12 + 30 = 42

The output y is 42, which does not match the given number of gallons. So, (3, 37) is not a valid ordered pair.

Answers

By following these steps, organizations can work towards bringing the process back under control and making it capable of producing output within the desired specifications.

Under statistical process control (SPC) and process capability analysis, if a process is determined to be out-of-control and not capable, the logical next step would be to first identify and address the sources of variation and special causes of variation in the process.

Here are the steps to follow:

Identify and eliminate special causes: Special causes are factors that cause unpredictable and non-random variation in the process. These causes need to be identified and eliminated or controlled. This may involve investigating specific factors such as equipment malfunction, operator error, or material defects that are leading to the out-of-control condition.

Stabilize the process: Once special causes have been identified and addressed, efforts should be made to stabilize the process. This involves reducing the sources of common cause variation, which are the inherent and predictable variations present in the process. Techniques such as process standardization, operator training, improved equipment maintenance, and standard operating procedures can be implemented to stabilize the process.

Assess process capability: After stabilizing the process, it is important to evaluate its capability to meet the desired specifications or requirements. Process capability analysis helps determine if the process is capable of consistently producing output within the desired tolerance limits. This analysis involves calculating process capability indices such as Cp, Cpk, or Pp, Ppk, and comparing them to the specified limits or customer requirements.

Implement process improvements: If the process is found to be incapable or not meeting the desired capability targets, process improvements need to be implemented. This may involve redesigning process parameters, adjusting equipment settings, improving material quality, or making other modifications to improve process performance and capability.

TRUE / FALSE. when the block is in equilibrium, each spring is stretched an additional ∆x. then the block is set into oscillation with amplitude a; when it passes through its equilibrium point it has a speed v.

Answers

The statement is true.

When the block is in equilibrium, each spring is stretched an additional ∆x. This implies that the forces from the two springs are balanced, and the block is not experiencing any net force in the equilibrium position.

When the block is set into oscillation with amplitude a, it will pass through its equilibrium point during the oscillation. At the equilibrium point, the displacement of the block is zero, and it changes direction. At this point, the block has its maximum speed v, as it is accelerating towards the equilibrium position.

The speed of the block decreases as it moves away from the equilibrium position, reaches zero at the maximum displacement (amplitude), and then starts accelerating towards the equilibrium point again. Therefore, when the block passes through its equilibrium point, it has its maximum speed v.

Answer:

Center: (5,8), Radius: [tex]\sqrt{10}[/tex]

Step-by-step explanation:

The explanation is attached below.

Answer:

To find the center and the radius of a circle that has a diameter with endpoints at (2, 7) and (8, 9), we can use the following steps:

1. Find the midpoint of the diameter using the formula: M = ((x1 + x2) / 2, (y1 + y2) / 2). This will give us the coordinates of the center of the circle. Plugging in the given endpoints, we get: M = ((2 + 8) / 2, (7 + 9) / 2) = (5, 8).

2. Find the length of the diameter using the distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2). This will give us the diameter of the circle. Plugging in the given endpoints, we get: d = sqrt((8 - 2)^2 + (9 - 7)^2) = sqrt(36 + 4) = sqrt(40).

3. Find the radius of the circle by dividing the diameter by 2: r = d / 2. This will give us the radius of the circle. Plugging in the value of d, we get: r = sqrt(40) / 2 = sqrt(10).

4. Write the equation of the circle using the standard form: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius. Plugging in the values of M and r, we get: (x - 5)^2 + (y - 8)^2 = 10.

Therefore, the center of the circle is (5, 8) and the radius is sqrt(10).

Develop a 99% coidence interval for the proportion of applicants that fail the test. (Round your answers to 3 decimal places) nfidence interval for the proportion mean is between and b. Would it be reasonable to conclude that 5% of the employees cannot pass the company policy test?

Answers

would be reasonable to conclude that less than 5% of the employees cannot pass the company policy test based on the given data.

To develop a 99% confidence interval for the proportion of applicants that fail the test, we can use the formula:

Confidence Interval = sample proportion ± margin of error

The sample proportion, denoted by p(cap), is calculated by dividing the number of failures (12) by the total number of tests (490):

p(cap) = 12/490 ≈ 0.0245

The margin of error, denoted by E, can be calculated using the formula:

E = Z * sqrt((p(cap) * (1 - p(cap))) / n)

Where:

Z is the critical value corresponding to the desired confidence level (99%),

sqrt represents the square root function,

p(cap) is the sample proportion,

n is the sample size (490).

To find the critical value Z, we can refer to the standard normal distribution table or use a statistical calculator. For a 99% confidence level, the critical value is approximately 2.576.

Substituting the values into the formula:

E = 2.576 * sqrt((0.0245 * (1 - 0.0245)) / 490) ≈ 0.0127

Now we can construct the confidence interval:

Confidence Interval = 0.0245 +/- 0.0127

Lower bound = 0.0245 - 0.0127 = 0.0118

Upper bound = 0.0245 + 0.0127 = 0.0372

Therefore, the 99% confidence interval for the proportion of applicants that fail the test is approximately 0.0118 to 0.0372.

b. To determine whether it would be reasonable to conclude that 5% of the employees cannot pass the company policy test, we can compare the proportion of failures (0.0245) with the given threshold of 0.05.

Since the lower bound of the confidence interval (0.0118) is less than 0.05, it suggests that the true proportion of employees failing the test could be lower than 5%.

Triangle GHJ and its image, triangle G’H’J’, are graphed on the coordinate grid below.

Answers

A rotation which occurred using the origin as the center of rotation is a rotation of 90° clockwise.

What is a rotation?

In Mathematics and Geometry, a rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

Next, we would apply a rotation of 90° clockwise to the coordinate of triangle GHJ in order to determine the coordinate of the vertices H' of the image, triangle G’H’J’;

(x, y)                               →            (y, -x)

Coordinate H = (3, 3) → H' = (3, -(3)) = H' (3, -3)

Answer:

There is no value but it really depends on the equation, Usually it is 1 if x is alone since the 1 is “ invisible “.

Twenty plots, each 10 by 4 meters; were randomly chosen in a large field of corn: For each plot; the plant density (number of plants in the plot; X) and the mean corn cob weight (in grams of grain per cob, Y) were observed and the following summary statistics are obtained from the study: 128.05, Ox = 32.61332, Vy = 224.10, Oy = 24.95448, R = 0.9418 Calculate the regression equation for this dataset Y = 403.882 1.231 Y = 403.88 + 1.231 Y = -316.3762 + 0.7206 Y = 316.3762 + 0.7206 Y = 316.3762 0.7206

Answers

The main answer to the question is Y = 316.3762 + 0.7206. This is the regression equation for the dataset, where Y represents the mean corn cob weight (in grams of grain per cob) and X represents the plant density (number of plants in the plot).

the explanation for this answer is that the regression equation was calculated using the summary statistics obtained from the study. The value of R, which represents the correlation coefficient, is 0.9418 indicating a strong positive correlation between X and Y. The slope of the regression line is 0.7206, meaning that for every unit increase in plant density, the mean corn cob weight increases by 0.7206 grams. The intercept is 316.3762, which represents the predicted mean corn cob weight when there are no plants in the plot. In conclusion, the regression equation for this dataset is Y = 316.3762 + 0.7206. This equation can be used to predict the mean corn cob weight based on the plant density in the plot. The strong positive correlation between X and Y suggests that increasing plant density can lead to an increase in the mean corn cob weight.

The x-terms in the system of equations are eliminated as follows:

3x + 5y = 5 -> Multiply by 2 on both sides.-2x - 8y = -6 -> Multiply by 3 on both sides.

How to solve the system of equations?

The system of equations in the context of this problem is defined as follows:

3x + 5y = 5.-2x - 8y = -6.

To solve the system, we use the elimination method, as we want to eliminate the variable x.

The least common factor of 3 and 2 is of 6, hence:

6/3 = 2.6/2 = 3.

Hence the variable x is eliminated as follows:

3x + 5y = 5 -> Multiply by 2 on both sides.-2x - 8y = -6 -> Multiply by 3 on both sides.

the minimum requirements for a class i aluminum main lightning conductor are ? strand size, 95 pounds/1,000 feet weight per length, and a cross-sectional area of 98,600 circular mils.

Answers

The minimum requirements for a class i aluminum main lightning conductor are a strand size, 95 pounds/1,000 feet weight per length, and a cross-sectional area of 98,600 circular mils.

These requirements are set by industry standards and regulations to ensure the safety and effectiveness of the lightning protection system. The strand size refers to the diameter of the individual wires that make up the conductor, which must meet a minimum size to withstand the forces of a lightning strike. The weight per length is a measure of the conductor's strength and durability, with a higher weight indicating a more robust design. Finally, the cross-sectional area is the total area of the conductor's circular shape, which impacts its ability to conduct electrical current and dissipate the energy from a lightning strike.

Overall, meeting these minimum requirements is essential for ensuring that a lightning protection system is capable of effectively capturing and directing the energy from a lightning strike to the ground, protecting the building and its occupants from potential harm.

the probability that an observation taken from a standard normal population will have a z value less than 0.5 and greater than ‒1.5, i.e., p(‒1.5

Answers

The probability that an observation taken from a standard normal population will have a z-value less than 0.5 and greater than -1.5 is approximately 0.6247, or 62.47%.

What is Probability?

Probability is a concept in mathematics and statistics that measures the likelihood of an event occurring.

To calculate the probability of an observation from a standard normal population having a z-value less than 0.5 and greater than -1.5, we need to find the area under the standard normal curve between these two z-values.

The standard normal distribution is symmetric, so we can use the properties of the distribution to determine the probability.

The z-value represents the number of standard deviations a particular observation is away from the mean. A z-value of 0 represents the mean, and positive z-values represent observations above the mean, while negative z-values represent observations below the mean.

To find the probability between two z-values, we can use the standard normal table or a calculator with a cumulative distribution function (CDF) for the standard normal distribution.

Using a standard normal table, we can find the probability corresponding to a z-value of 0.5, which is approximately 0.6915. Similarly, the probability corresponding to a z-value of -1.5 is approximately 0.0668.

To find the probability between these two z-values, we subtract the probability corresponding to the lower z-value from the probability corresponding to the higher z-value:

P(-1.5 < z < 0.5) = P(z < 0.5) - P(z < -1.5)

= 0.6915 - 0.0668

= 0.6247

Therefore, the probability that an observation taken from a standard normal population will have a z-value less than 0.5 and greater than -1.5 is approximately 0.6247, or 62.47%.
