Consider the following information on a portfolio of three stocks: a. If your portfolio is invested 36 percent each in A and B and 28 percent in C, what is the portfolio's expected return, the variance, and the standard deviation? Note: Do not round intermediate calculations. Round your variance answer to 5 decimal places, e.g., 16161 . Enter your other answers as a percent rounded to 2 decimal places, e.g., 32.16. b. If the expected T-bill rate is 4.35 percent, what is the expected risk premium on the portfolio? Note: Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16
