Consider the following table Bond Fund Rate of Return 11% 17% 10% 701 Stock Fund Rate of Return Probability 0.05 0.25 0.40 0.30 Scenario Severe recession Mild recession Normal growth Boom -26% -6% 11% 16% 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 6.40 % 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 calculation. Round your answer to 2 decimal places.) Covariance
