Suppose the expected returns and standard deviations of Stocks A and B are E(RA) = .096, E(RB) = .156, σA = .366, and σB = .626.

a-1. Calculate the expected return of a portfolio that is composed of 41 percent Stock A and 59 percent Stock B when the correlation between the returns on A and B is .56. (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

b. Calculate the standard deviation of a portfolio with the same portfolio weights as in part (a) when the correlation coefficient between the returns on Stocks A and B is −.56. (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
