Consider an equation to explain salaries of CEOs in terms of annual firm sales in million dollars, return on equity (roe, measured in percentage points as the unit), and return on the firm's sock (ros, measured in percentage points as the unit):

Asume that the following equation was obtained by OLS:

By how much is salary predicted to increase on average if ros increases by 30 percentage points while all other variables are held constant?

(Please indicate the solution this way: "66" and do not write down the symbol %. Indicate an increase with the number and a decrease with a "-" in front of the number)

1. In C++, there are 4 students that are running for class president. Create three arrays: the candidate’s name, the number of votes the candidate receives, and the candidate’s percentage of the total votes. Your program should be broken down into at least 3 functions: find the total number of votes, calculate values for the percentage each candidate received, and sort the number of votes from highest to lowest. Write the candidate’s name, the total number of votes they received, and the percentage of the total using the following: Joe 20 Bill 30 Sue 40 Mary 35

A random sample of 145 recent donations at a certain blood bank reveals that 81 were type A blood. Does this suggest that the actual percentage of type A donations differs from 40%, the percentage of the population having type A blood? Carry out a test of the appropriate hypotheses using a significance level of 0.01.
State the appropriate null and alternative hypotheses.

H₀: p = 0.40
H_a: p > 0.40 H₀: p = 0.40
H_a: p < 0.40     H₀: p = 0.40
H_a: p ≠ 0.40 H₀: p ≠ 0.40
H_a: p = 0.40

Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.)

State the conclusion in the problem context.

Reject the null hypothesis. There is not sufficient evidence to conclude that the percentage of type A donations differs from 40%. Do not reject the null hypothesis. There is sufficient evidence to conclude that the percentage of type A donations differs from 40%.     Reject the null hypothesis. There is sufficient evidence to conclude that the percentage of type A donations differs from 40%. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the percentage of type A donations differs from 40%.

Would your conclusion have been different if a significance level of 0.05 had been used?

Yes No    

You may need to use the appropriate table in the Appendix of Tables to answer this question.

How profitable are different sectors of the stock market? One way to answer such a question is to examine profit as a percentage of stockholder equity. A random sample of 25 retail stocks such as Toys 'R' Us, Best Buy, and Gap was studied for x₁, profit as a percentage of stockholder equity. The result was x₁ = 14.8. A random sample of 30 utility (gas and electric) stocks such as Boston Edison, Wisconsin Energy, and Texas Utilities was studied for x₂, profit as a percentage of stockholder equity. The result was x₂ = 10.0. Assume that σ₁ = 4.9 and σ₂ = 2.3.

Categorize the problem below according to parameter being estimated, proportion p, mean μ, difference of means μ₁ – μ₂, or difference of proportions p₁ – p₂. Then solve the problem.

pμ₁ – μ₂    p₁ – p₂μ

(b) Let μ₁ represent the population mean profit as a percentage of stockholder equity for retail stocks, and let μ₂ represent the population mean profit as a percentage of stockholder equity for utility stocks. Find a 95% confidence interval for μ₁ – μ₂. (Use 1 decimal place.)

(c) Examine the confidence interval and explain what it means in the context of this problem. Does the interval consist of numbers that are all positive? all negative? of different signs? At the 95% level of confidence, does it appear that the profit as a percentage of stockholder equity for retail stocks is higher than that for utility stocks?

1.) The Heating Division of Kobe International produces a heating element that it sells to its customers for $47 per unit. Its variable cost per unit is $30, and its fixed cost per unit is $8. Top management of Kobe International would like the Heating Division to transfer 14,700 heating units to another division within the company at a price of $35. The Heating Division is operating at full capacity. Assume that the units being requested are special high-performance units and that the division's variable cost would be $24 per unit (rather than $30). What is the minimum transfer price that the Heating Division should accept?

Minimum transfer price =
