Suppose the expected returns and standard deviations of Stocks A and B are E(R_A) = .093, E(R_B) = .153, ?_A = .363, and ?_B = .623.

a-1.	Calculate the expected return of a portfolio that is composed of 38 percent A and 62 percent B when the correlation between the returns on A and B is .53. (Do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))
