R -a . e where is the excess return for security and Ry is the market's excess return. The risk-free rate is 4%. Suppose also that there are three securities A B. and characterized by the following data: Security Pi (R1) 0/) 0.5 21 21 c 1.3 20 15 a. If ox- 18%, calculate the variance of returns of securities A. Variance Security Security B Security C ences b. Now assume that there are an infinite number of assets with return characteristics identical to those of A, B, and respectively What will be the mean and variance of excess returns for securities A B and C7 (Enter the variance answers as a percent squared and mean as a percentage. Do not round intermediate calculations. Round your answers to the nearest whole number.) Mean Variance Security A Secu Security C
