(a-1) The value of the population mean is unknown.

(a-2) The best estimate of the population mean is the sample mean, which is 20 eggs.

(c) The value of t for a 95% confidence interval with 17 degrees of freedom is approximately 2.110.

(d) the 95% confidence interval for the population mean is approximately (17.902, 22.098).

(e-1) It would not be reasonable to conclude that the population mean is 17 eggs.

(e-2) It would be reasonable to conclude that the population mean is 18 eggs.

(a-1) The given information provides the sample mean (20 eggs) and the sample standard deviation (5 eggs), but it does not directly provide the population mean.

(a-2) In the absence of other information, the sample mean is a reasonable estimate of the population mean.

(c) For a 95% confidence interval, the value of t can be determined using the t-distribution with n-1 degrees of freedom, where n is the sample size. In this case, the sample size is 18, so the degrees of freedom is 18 - 1 = 17.

Using a t-distribution table or a statistical software, the value of t for a 95% confidence interval with 17 degrees of freedom is approximately 2.110.

(d) To determine the 95% confidence interval for the population mean, we can use the formula: Confidence interval = sample mean ± (t * standard error), where the standard error is the sample standard deviation divided by the square root of the sample size.

In this case, the sample mean is 20, the standard deviation is 5, the sample size is 18, and the value of t is 2.110. Plugging in these values, the confidence interval is 20 ± (2.110 * (5 / √18)), which evaluates to approximately 20 ± 2.098.

(e-1) The 95% confidence interval calculated in part (d) does not include 17 eggs, indicating that it is unlikely for the population mean to be 17 eggs.

(e-2) The 95% confidence interval calculated in part (d) includes 18 eggs, suggesting that it is plausible for the population mean to be 18 eggs.

If m∠2 =(3x+2)° and m∠3 = 100° and the angle is linear pairs the value of x will be 26°.

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

It is given that,

m∠2 =(3x+2)°

m∠3 = 100

If the ∠2 and ∠3 are linear pairs the sum of the angles is 180°.

Only when a pair of neighboring angles add up to 180 degrees is the pair referred to be a linear angle. For instance, the sum of the neighboring linear angles of 40 degrees and 140 degrees will equal 180 degrees, making them known as linear angles.

∠2 + ∠3 = 180°

(3x+2) + 100 = 180°

(3x+2) = 180° - 100

(3x+2) = 80

3x = 80 -2

3x =78

x =26

Thus, if m∠2 =(3x+2)° and m∠3 = 100° and the angle is linear pairs the value of x will be 26°.

Rounding up to the nearest unit, it would take Calvin approximately 27 months to pay off his credit card with a monthly payment of $165.

To determine how long it would take Calvin to pay off his credit card, we need to consider the monthly payment amount and the interest rate. Let's calculate the time it would take for two different monthly payment amounts: $220 and $165.

a. Monthly payment of $220:

Let's assume the initial balance on Calvin's credit card is $3,000, and the annual interest rate is 4 percent. To calculate the monthly interest rate, we divide the annual interest rate by 12 (number of months in a year):

Monthly interest rate = 4% / 12 = 0.3333%

Now, we can calculate the time it would take to pay off the credit card using the monthly payment of $220 and the monthly interest rate. We'll use a formula for the number of months required to pay off a loan with fixed monthly payments:

n = -(log(1 - (r * P) / A) / log(1 + r))

Where:

n = number of months

r = monthly interest rate (as a decimal)

P = initial balance

A = monthly payment

Plugging in the values:

n = -(log(1 - (0.003333 * 3000) / 220) / log(1 + 0.003333))

Using a calculator, we can find:

n ≈ 15.34

Rounding up to the nearest unit, it would take Calvin approximately 16 months to pay off his credit card with a monthly payment of $220.

b. Monthly payment of $165:

We can repeat the same calculation using a monthly payment of $165:

n = -(log(1 - (0.003333 * 3000) / 165) / log(1 + 0.003333))

Using a calculator, we find:

n ≈ 26.39

Please note that these calculations assume that Calvin does not make any additional charges on his credit card during the repayment period. Additionally, the interest rate and the balance are assumed to remain constant. In practice, these factors may vary and could affect the actual time required to pay off the credit card balance.

Predictive accuracy and goodness-of-fit are not the same because they assess different aspects of a predictive model. Predictive accuracy focuses on how well a model predicts outcomes on new, unseen data, while goodness-of-fit measures how well a model fits the observed data used for training.

Strategies like holdout, cross-validation, and bootstrap sampling support predictive performance evaluation by providing methods to estimate how well a model will generalize to new data. Holdout involves splitting the data into training and testing sets, allowing the model to be evaluated on unseen data. Cross-validation further enhances this by performing multiple iterations of holdout with different train-test splits, providing more robust performance estimates. Bootstrap sampling generates multiple bootstrap samples from the original data, allowing for the calculation of confidence intervals and assessing model stability.

The problem involves analyzing two regression models in the context of real estate data. The first model relates selling price to the size of the home, while the second model relates days-on-the-market to the price of the home.

In the first model, the regression equation is obtained by fitting a line to the data, with selling price as the dependent variable and the size of the home as the independent variable. The equation will provide the estimated relationship between these variables. Using this equation, the selling price for a home with an area of 2,200 square feet can be estimated.

For the 95% confidence interval for all 2,200-square-foot homes, the interval will provide a range within which the true mean selling price lies. Similarly, the 95% prediction interval for the selling price of a home with 2,200 square feet will provide a range within which an individual selling price is likely to fall.

In the second model, the regression equation relates days-on-the-market to the price of the home. By fitting a line to the data, we can determine the equation and estimate the days-on-the-market for a home priced at $300,000.

The 95% confidence interval for homes with a mean price of $300,000 provides a range within which the true mean days-on-the-market lies. The 95% prediction interval for a home priced at $300,000 gives a range within which an individual days-on-the-market value is likely to fall.

To determine how long it will take the Baxter boys to prepare 131 papers, we can use the concept of rate and proportion.

It will take approximately 11 minutes and 14 seconds (to the nearest minute) for the Baxter boys to prepare 131 papers. Given that the Baxter boys can prepare 35 papers in 3 minutes, we can set up a proportion to solve for the time it will take to prepare 131 papers.
First, let's set up the proportion using the information given about the rate of working:
35 papers / 3 minutes = 131 papers / x minutes
To solve for x, we can cross-multiply and then divide:
35 * x = 3 * 131
35x = 393
x = 393 / 35
x ≈ 11.229

The dividend in 2018 was $2.95, and it is expected to grow at a rate of 7.4% for the next five years and 2.6% thereafter. With an equity cost of capital of 8.6%, the value per share at the end of 2018 can be calculated.

To calculate the value per share at the end of 2018, we need to discount the expected future dividends using the dividend-discount model. The model assumes that the value of a stock is equal to the present value of all its expected future dividends.

First, we need to calculate the dividends for each year from 2019 to 2023. We start with the dividend in 2018, which was $2.95. We then increase it by 7.4% each year for the next five years:

Dividend in 2019 = $2.95 * (1 + 7.4%) = $3.17

Dividend in 2020 = $3.17 * (1 + 7.4%) = $3.40

Dividend in 2021 = $3.40 * (1 + 7.4%) = $3.65

Dividend in 2022 = $3.65 * (1 + 7.4%) = $3.92

Dividend in 2023 = $3.92 * (1 + 7.4%) = $4.22

After 2023, the dividend is expected to grow at a rate of 2.6% per year. To find the value per share at the end of 2018, we discount the future dividends to their present value using the equity cost of capital of 8.6%.

The present value of the dividends can be calculated as follows:

PV = (D1 / (1 + r)) + (D2 / (1 + r)^2) + ... + (Dn / (1 + r)^n)

where PV is the present value, D1 to Dn are the dividends for each year, r is the equity cost of capital, and n is the number of years.

In this case, n = 5 because we are discounting the dividends for the next five years. Let's calculate the present value:

PV = ($3.17 / (1 + 8.6%)) + ($3.40 / (1 + 8.6%)^2) + ($3.65 / (1 + 8.6%)^3) + ($3.92 / (1 + 8.6%)^4) + ($4.22 / (1 + 8.6%)^5)

PV = $3.17 / 1.086 + $3.40 / 1.086^2 + $3.65 / 1.086^3 + $3.92 / 1.086^4 + $4.22 / 1.086^5

PV ≈ $2.91 + $3.07 + $3.24 + $3.41 + $3.59

PV ≈ $16.22

Therefore, the estimated value per share of Procter and Gamble at the end of 2018 using the dividend-discount model is approximately $16.22.

Step-by-step explanation:

The slope of a line perpendicular to the line of x + 4y = 16 is 4.

Given the equation of line;

x + 4y = 16

First, rearrange in slope intercept form ( y = mx + b ) by solving for y

x + 4y = 16

Subtract x from both sides

x - x + 4y = 16 - x

4y = -x + 16

Divide each term by 4 and simplify

4y/4 = -x/4 + 16/4

y = -(1/4)x + 4

Using the slope intercept form ( y = mx + b ) to compare.

y = -(1/4)x + 4

Slope m = -(1/4)

Now, the equation of a perpendicular line to y = -(1/4)x + 4 must have a slope that is the negative reciprocal of the original slope.

Hence, m_perpendicular will be;

m_perpendicular = -( 1 / original slope )

m_perpendicular = -( 1 / -(1/4) )

m_perpendicular = -( -4 )

m_perpendicular = 4

Therefore, the slope of a line perpendicular to the line of x + 4y = 16 is 4.

To maximize the amount of peaches produced by the orchard, the peach orchard owner should plant a certain number of trees per acre. The per-tree yield is given by the equation Y = 1200 - 15x, where Y represents the yield per tree and x represents the number of trees planted per acre.

To find the number of trees per acre that maximizes the crop yield, we need to determine the value of x that corresponds to the vertex of the equation. The vertex of a downward-opening parabola, represented by the given equation, occurs at the x-coordinate given by x = -b / (2a).

In this case, the coefficient of x is -15 and the constant term is 0, so b = 0 and a = -15. Substituting these values into the formula, we get x = -0 / (2 * -15) = 0.

While the mathematical calculation suggests that planting zero trees per acre would maximize the yield, this result is not practical. Therefore, the closest feasible value greater than zero would be 1 tree per acre.

For 1 tree per acre, substituting x = 1 into the equation, we find that each tree would produce a yield of Y = 1200 - 15 * 1 = 1185 peaches. Consequently, the resulting total yield would be 1185 peaches per acre.
