Suppose that the index model for stocks A and B is estimated from excess returns with the following results: R_A = 3.6% + 1.20R_M + e_A R_B = 1.6% + 1.50R_M + e_{B M} = 16%; R-square_A = 0.25; R-square_B = 0.15 Break down the variance of each stock to the systematic and firm-specific components. (Do not round intermediate calculations. Calculate using numbers in decimal form, not percentages. Round your answers to 4 decimal places.)
