(b) Calculate the standard deviations (?) for both X and Y. (c) Calculate the coefficient of variation (CV) for both X and Y. (d) If you were to create a portfolio consisting of 67% of Stock X and 33% of Stock Y, what will be the expected return (rP) and the standard deviation (?P) for your portfolio
