Consider the following information on the expected return for companies X and Y.

Economy	Probability		X				Y
Boom	0.16			37	%			17	%
Neutral	0.50			12	%			25	%
Poor	0.34			25	%			9	%

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.)

	Company X		Company Y
Expected value		%		%
Standard deviation		%		%

b. Calculate the correlation coefficient if the covariance between X and Y is 99. (Round your answer to 4 decimal places.)
