With a little care, you can find the median and the quartiles from the histogram. what are these numbers? you can also find the mean number of servings of fruit claimed per day from the histogram. first use the information in the histogram to compute the sum of the 74 observations, and then use this to compute the mean.
Complete Question
The histogram from this question is shown on the first uploaded image
Answer:
The first quartile is [tex]1st Q = 19^{th} girl (subject ) = 1 \serving\ of\ fruit\ per\ day[/tex]
The median is [tex]Median = 38 ^{th} \ girl (subject) = 2 \serving\ of\ fruit\ per\ day [/tex]
The third quartile is [tex]3rd Q = 56^{th} \ girl (subject) = 4 \serving\ of\ fruit\ per\ day [/tex]
The mean is [tex]\= x = 2.62[/tex]
Step-by-step explanation:
From the question we are told that
The total number of girls is n = 74
Generally the median is mathematically represented as
[tex]Median = \frac{\frac{n}{2} +[ \frac{n}{2} + 1] }{2}[/tex]
So
[tex]Median = \frac{\frac{74}{2} +[ \frac{74}{2} + 1] }{2}[/tex]
=> [tex]Median = \frac{37 +38 }{2}[/tex]
=> [tex]Median =37.5 \ girl [/tex]
From the histogram [tex]37.5 \approx 38^{th} \ girl[/tex] fall under 2 fruits per day
Generally the first quartile is mathematically represented as
[tex]1st \ Q = \frac{\frac{n}{4} + [\frac{n}{4} + 1] }{2}[/tex]
=> [tex]1st \ Q = \frac{\frac{74}{4} + [\frac{74}{4} + 1] }{2}[/tex]
=> [tex]1st \ Q = 19 \ girl [/tex]
From the histogram [tex]19^{th} [/tex]girl fall under 1 fruit per day
Generally the third quartile is mathematically represented as
[tex]3rd\ Q = \frac{\frac{n}{2} + n }{2}[/tex]
=> [tex]3rd\ Q = \frac{\frac{74}{2} + 74 }{2}[/tex]
=> [tex]3rd\ Q = 55.5 [/tex]
From the histogram [tex]55.5 \approx 56^{th} \ girl[/tex] fall under 4 fruits per day
Generally from the histogram table the frequency [number of subjects (girls) ] and the servings of fruit per day can be represented as
Total
x(servings per day ) 0 1 2 3 4 5 6 7 8
f (number of subjects ) 15 11 15 11 8 5 3 3 3 [tex]\sum f = 74[/tex]
xf 0 11 30 33 32 25 18 21 24 [tex]\sum xf = 194[/tex]
Generally the mean is mathematically represented as
[tex]\= x = \frac{1}{ \sum f} * [\sum xf][/tex]
=> [tex]\= x = \frac{1}{ 74} *194[/tex]
=> [tex]\= x = 2.62[/tex]

Compute the future worth for the following cash flows. 5x 4x 3x 2x i = 12 % x
To compute the future worth of the given cash flows, we need to multiply each cash flow by its corresponding discount factor and sum them up. The discount factor can be calculated using the formula:
Discount Factor = 1 / (1 + i)^n
Where:
i is the interest rate (12% or 0.12 in decimal form)
n is the number of periods
Let's calculate the future worth step by step:
Cash Flow: 5x
Discount Factor = 1 / (1 + 0.12)^1 = 1 / 1.12 = 0.8929 (rounded to 4 decimal places)
Future Worth of 5x = 5x * 0.8929 = 4.4645x
Cash Flow: 4x
Discount Factor = 1 / (1 + 0.12)^2 = 1 / 1.2544 = 0.7972 (rounded to 4 decimal places)
Future Worth of 4x = 4x * 0.7972 = 3.1888x
Cash Flow: 3x
Discount Factor = 1 / (1 + 0.12)^3 = 1 / 1.4049 = 0.7118 (rounded to 4 decimal places)
Future Worth of 3x = 3x * 0.7118 = 2.1354x
Cash Flow: 2x
Discount Factor = 1 / (1 + 0.12)^4 = 1 / 1.5735 = 0.6355 (rounded to 4 decimal places)
Future Worth of 2x = 2x * 0.6355 = 1.2710x
Now, let's sum up all the future worth values:
Future Worth = 4.4645x + 3.1888x + 2.1354x + 1.2710x
= 11.0597x
Therefore, the future worth of the given cash flows is 11.0597x.

(d) If the etror term is mean independent from the regressors x 1,x 2 and x 3
, then we can claim that the OLS estimator
β is unbiased and that each of the entimated parameters are measuring caisal effects. ( 14 points)
The statement provided is false. The assumption that the error term is mean independent from the regressors x1, x2, and x3, also known as exogeneity, is a crucial assumption for Ordinary Least Squares (OLS) regression. However, this assumption alone does not guarantee that the OLS estimator β is unbiased or that each estimated parameter measures causal effects.
Unbiasedness of the OLS estimator relies on several assumptions, including exogeneity, but it also requires other conditions to hold. One important condition is that the error term has zero conditional mean given the regressors. This condition, known as the conditional expectation of errors being zero (E[ε|X] = 0), ensures that there is no systematic bias in the estimation.
Causal interpretation of the estimated parameters requires additional assumptions beyond exogeneity. In order to establish causal effects, researchers often rely on a combination of study design, theory, and additional assumptions such as the absence of omitted variable bias, correct specification of the functional form, and correct model identification.
Therefore, while exogeneity is an important assumption for OLS regression, it alone does not guarantee unbiasedness of the estimator or the ability to interpret estimated parameters as causal effects. Other assumptions and considerations are necessary to make such claims.

Use the applet to build cubes that result from dilating a unit cube by each scale factor shown in the table. Then, complete the table with the surface area and volume of each dilated cube. scale factor surface area in square units volume in cubic units
By using an applet, cubes can be constructed by dilating a unit cube with different scale factors. The table is then completed by calculating the surface area and volume of each dilated cube.
Dilating a cube involves scaling it uniformly in all dimensions by a certain factor. To complete the table with the surface area and volume of each dilated cube, we can use the following steps:
Use the applet to construct a unit cube, which has a side length 1 unit.
Apply each scale factor listed in the table to dilate the unit cube. This means multiplying each side length of the unit cube by the corresponding scale factor.
Calculate the surface area of each dilated cube. The surface area of a cube can be found by multiplying the area of one face by 6, as a cube has 6 equal faces.
Calculate the volume of each dilated cube. The volume of a cube is found by cubing the length of one side.
Fill in the table with the surface area and volume of each dilated cube corresponding to its scale factor.
By following these steps, we can construct cubes of different sizes by dilating the unit cube and determining their surface area and volume. The table will provide the measurements for each dilated cube based on the given scale factors.

Write the equation in slope-intercept form that corresponds with this table.
The equation in slope-intercept form is therefore:y = mx + b = -x + 4
To write the equation in slope-intercept form that corresponds with the given table, we need to use the slope-intercept formula which is:y = mx + b
where m represents the slope and b represents the y-intercept.The slope formula is given bym = (y2 - y1)/(x2 - x1)where (x1, y1) and (x2, y2) are two points on the line.
To get the equation in slope-intercept form, we need to find the slope and y-intercept from the given table. Then we'll substitute the values of m and b in the slope-intercept formula and solve for y.
Let's first identify two points from the table. We can use any two points on the line. Let's use (0, 4) and (2, 2) as they have nice values for calculations.Using the slope formula, we have:
m = (y2 - y1)/(x2 - x1) = (2 - 4)/(2 - 0) = -2/2 = -1

Given that z is a standard normal random variable, compute the following probabilities. calculate P(1
You can approximate the probability using the standard normal distribution table by looking up the closest values for Φ(2) and Φ(1).
To calculate the probability P(1 < z < 2) for a standard normal random variable, we can use the cumulative distribution function (CDF) of the standard normal distribution.
The CDF gives us the probability that a standard normal random variable is less than or equal to a given value. We can use this information to calculate the probability between two values.
Let's denote the CDF of the standard normal distribution as Φ(z). The probability P(1 < z < 2) can be calculated as follows:
P(1 < z < 2) = Φ(2) - Φ(1)
To calculate this, we need to look up the values of Φ(2) and Φ(1) from a standard normal distribution table or use a calculator/computer software. However, since I don't have access to real-time computations in this environment, I am unable to provide the exact numerical value.
But you can use statistical software or online calculators to find the precise value. Alternatively, you can approximate the probability using the standard normal distribution table by looking up the closest values for Φ(2) and Φ(1).

A certain plane is described by 2x+3y+4z=16. Find the unit vector normal to the surface in the direction away from the origin.
A certain plane is described by 2x+3y+4z=16. Find the unit vector normal to the surface in the direction away from the origin.Firstly, we will obtain the coefficients of the x, y and z variables from the equation of the plane:2x + 3y + 4z = 16The coefficients are 2, 3, and 4 respectively.
Now, we will calculate the magnitude of the normal vector, ||N||, using the formula:||N|| = √(a² + b² + c²)where a, b, and c are the coefficients of the x, y, and z variables respectively.||N|| = √(2² + 3² + 4²)= √(4 + 9 + 16)= √29Therefore, the unit normal vector in the direction away from the origin is given by:N = (2/√29) i + (3/√29) j + (4/√29) k. Given the equation of a plane as 2x + 3y + 4z = 16, we have to find the unit vector normal to the surface in the direction away from the origin. Here's how we can do it:To find the unit vector normal to the surface, we first need to find the coefficients of the x, y, and z variables from the equation of the plane. In this case, the coefficients are 2, 3, and 4 respectively.Next, we can use the formula ||N|| = √(a² + b² + c²) to calculate the magnitude of the normal vector, where a, b, and c are the coefficients of the x, y, and z variables respectively. In this case, ||N|| = √(2² + 3² + 4²) = √29.Finally, we can find the unit normal vector in the direction away from the origin by dividing each coefficient by the magnitude of the normal vector, ||N||. Thus, the unit normal vector is:N = (2/√29) i + (3/√29) j + (4/√29) k
Therefore, the unit vector normal to the surface in the direction away from the origin is (2/√29) i + (3/√29) j + (4/√29) k.

plot 5–11 the failure locus, the load line, and estimate the factor of safety by graphical measurement
To plot the failure locus and load line, we need specific data points or equations that define them. The failure locus represents the failure criterion or limit for a given material or structure, and the load line represents the applied loads or stresses. Without this information, we cannot plot them accurately.
Once the failure locus and load line are plotted, we can estimate the factor of safety by measuring the distance between the failure locus and the load line at a specific point. The factor of safety is typically calculated as the ratio of the ultimate strength or capacity of a structure to the applied loads. By measuring the distance between the failure locus and the load line, we can determine the margin of safety.
Please provide the necessary data or equations for the failure locus and load line so that we can assist you further in plotting and estimating the factor of safety.
