Consider the following information on the expected return for
companies X and Y.
Economy | Probability | X | Y | ||||||
Boom | 0.24 | 33 | % | 18 | % | ||||
Neutral | 0.59 | 11 | % | 22 | % | ||||
Poor | 0.17 | −35 | % | 4 | % | ||||
a. Calculate the expected value and the standard
deviation of returns for companies X and Y. (Round
intermediate calculations to at least 4 decimal places. Round your
final answers to 2 decimal places.)
b. Calculate the correlation coefficient if the
covariance between X and Y is 188. (Round your answer to 4
decimal places.)
