1. You are given the option of choosing between three well diversified portfolios to use as the optimal portfolio in a single index model.    Information on them is given below:

1. (20 points) If the risk-free rate is .04, which portfolio would you choose? Why?
2. (20 points) How, if at all, does your answer change if the risk-free rate is .06? Explain.

The expected pretax return on three stocks is divided between dividends and capital gains in the following way:

Required:

a. If each stock is priced at $200, what are the expected net percentage returns on each stock to (i) a pension fund that does not pay taxes, (ii) a corporation paying tax at 21% (the effective tax rate on dividends received by corporations is 6.3%), and (iii) an individual with an effective tax rate of 15% on dividends and 10% on capital gains?

b. Suppose that investors pay 50% tax on dividends and 20% tax on capital gains. If stocks are priced to yield an after-tax return of 8%, what would A, B, and C each sell for? Assume the expected dividend is a level perpetuity.

To test for any significant difference in the number of hours between breakdowns for three machines, the following dataset was obtained:

If each stock is priced at $175, what are the expected net percentage returns on each stock to (i) a pension fund that does not pay taxes, (ii) a corporation paying tax at 21% (the effective tax rate on dividends received by corporations is 6.3%), and (iii) an individual with an effective tax rate of 10% on dividends and 5% on capital gains?

b. Suppose that investors pay 40% tax on dividends and 10% tax on capital gains. If stocks are priced to yield an after-tax return of 10%, what would A, B, and C each sell for? Assume the expected dividend is a level perpetuity.

A researcher wants to see if there are any differences between three types of studying: Studying in a quiet room, studying in a room with classical music playing, and studying in a room with loud lawn equipment going on outside the window. She recruits 9 college students and puts three in each group. She has them read an excerpt from a physics textbook and then gives them a 5-question quiz. Below are their scores. Does study condition have an effect on academic performance?
