b. A portfolio that combines the risk-free asset and the market portfolio has an expected return of
7 percent and a standard deviation of 10 percent. The risk-free rate is 4 percent, and the
expected return on the market portfolio is 12 percent. Assume the capital asset pricing model
holds. What expected rate of return would a security earn if it had a .45 correlation with the
market portfolio and a standard deviation of 55 percent?
c. Suppose the risk-free rate is 4.2 percent and the market portfolio has an expected return of 10.9
percent. The market portfolio has a variance of .0382. Portfolio Z has a correlation coefficient
with the market of .28 and a variance of 3285. According to the capital asset pricing model,
what is the expected return on Portfolio Z?
