 A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a sure rate of 4.4%. The probability distributions of the risky funds are:  | 
| Expected Return | Standard Deviation | |||
| Stock fund (S) | 14 | % | 34 | % | 
| Bond fund (B) | 5 | % | 28 | % | 
| The correlation between the fund returns is .0214. | 
| 
 Suppose now that your portfolio must yield an expected return of 13% and be efficient, that is, on the best feasible CAL.  | 
| a. | 
 What is the standard deviation of your portfolio?  | 
| b-1. | 
 What is the proportion invested in the T-bill fund?  | 
| b-2. | 
 What is the proportion invested in each of the two risky funds?  |
