The standard deviation of the market-index portfolio is 20%. Stock A has a beta of 2.80 and a residual standard deviation of 30%.

a. Calculate the total variance for an increase of 0.25 in its beta. (Do not round intermediate calculations. Round your answer to the nearest whole number.)

Total variance _______ %-Squared

b. Calculate the total variance for an increase of 8.54% in its residual standard deviation. (Do not round intermediate calculations. Round your answer to the nearest whole number.)

Total variance_______  %-Squared
