(4 points) What is the systematic risk of stock i and stock j respectively? c. (4 points) What is the firm specific risk (namely unsystematic risk) of stock i and stock j respectively? d. (3 points) What is the total risk of stock i and stock j respectively? e. (3 points) What fraction of stock i's total variance can be diversified? What fraction of stock j's total variance can be diversified? f. (4 points) What is the covariance and correlation between stocks i and j
