Consider the following table: Stock Fund Rate of Return Bond Fund Rate of Return Scenario Probability 0.05 Severe recession -26% -11% Mild recession 0.25 -6% 17% 10% Normal growth Boom 0.40 0.30 11% 16% -7% Required: 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.) % Mean return Variance b. Calculate the value of the covariance between the stock and bond funds.
