a. Suppose you hold an equally weighted portfolio of 100 stocks with the same alpha, beta, and residual standard deviation as
Waterworks. Assume the residual returns on each of these stocks are independent of each other. What is the residual standard
deviation of the portfolio? (Round your answer to 1 decimal place.)
Residual standard deviation
