he following are estimates for two stocks.

Stock	Expected Return			Beta	Firm-Specific Standard Deviation
A		8	%	1.10		25	%
B		16		1.60		36

The market index has a standard deviation of 18% and the risk-free rate is 6%.

a. What are the standard deviations of stocks A and B? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

b. Suppose that we were to construct a portfolio with proportions:

Stock A	0.30
Stock B	0.45
T-bills	0.25

Compute the expected return, standard deviation, beta, and nonsystematic standard deviation of the portfolio. (Do not round intermediate calculations. Enter your answer for Beta as a number, not a percent. Round your answers to 2 decimal places.)
