The probability distribution of the risky funds is as follows: Stock fund (S) Bond fund (B) Expected Return 228 14 Standard Deviation 378 23 The correlation between the fund returns is 0.10. You require that your portfolio yield an expected return of 15%, and that it be efficient, on the best feasible CAL. a. What is the standard deviation of your portfolio? (Round your answer to 2 decimal places.) Answer is complete but not entirely correct. Standard deviation 27.65 % b. What is the proportion invested in the T-bill fund and each of the two risky funds?
