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 5.9%. The probability distributions of the risky funds are:

	Expected Return		Standard Deviation
Stock fund (S)	20	%	49	%
Bond fund (B)	9	%	43	%

The correlation between the fund returns is .0721.

Suppose now that your portfolio must yield an expected return of 18% and be efficient, that is, on the best feasible CAL.

a.	What is the standard deviation of your portfolio? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
