Suppose that you want to create a portfolio that consists of a corporate bond? fund, X, and a common stock? fund, Y. For a? $1,000 investment, the expected return for X is $ 75 and the expected return for Y is $ 100. The variance for X is 1,575 and the variance for Y is 13,275. The covariance of X and Y is 3,065.

Complete parts? (a) through? (d).
