scenario	prob.	stock fund rate of return %	bond fund rate of return %
severe recession	.05	-29	-14
mild recession	.25	-9	20
normal growth	.4	14	13
boom	.3	19	-10

Consider the following table: Stock Fund Bond Fund Scenario Probability Rate of Return Rate of Return Severe recession 0.05 29 % 14 % Mild recession 0.25 9 % 20 % Normal growth 0.40 14 % 13 % Boom 0.30 19 % 10 %

a.Calculate the values of mean return and variance for the stock fund. (Do not round intermediate calculations. Round "Mean return" value to 1 decimal place and "Variance" to 2 decimal places.)

b.Calculate the value of the covariance between the stock and bond funds.
