Suppose the expected returns and standard deviations of Stocks A and B are E(RA) = .092, E(RB) = .152, σA = .362, and σB = .622. a-1. Calculate the expected return of a portfolio that is composed of 37 percent A and 63 percent B when the correlation between the returns on A and B is .52. (Do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))
