Consider the following table Stock Fund Rate of Return Probability 0.10 0.20 0.40 0.30 Bond Fund Rate of Return -11% 17% 10% Scenario Severe recession Mild recession Normal growth Boom -38% -18% 25% 28% b. Calculate the values of mean return and variance for the stock fund. (Do not round intermediate calculations. Round "Mean return" value to 2 decimal place and "Variance" to 2 decimal places.) Mean return 10.20 % Variance c. Calculate the value of the covariance between the stock and bond funds. (Negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to 2 decimal places.) Covariance
