Consider the following table: Stock Fund Bond Fund Scenario Probability Rate of Return Rate of Return Severe recession 0.05 −36% −11% Mild recession 0.20 −12% 13% Normal growth 0.40 15% 4% Boom 0.35 32% 5% b. 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 4 decimal places.)
