Consider the following table: Scenario Severe recession Mild recession Normal growth Boom Probability 0.10 0.20 0.40 0.30 Stock Fund Rate of Return -36% -16% 21% 26% Bond Fund Rate of Return -9% 15% 8% -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 2 decimal places.) Mean return Variance 9.4 % 471.64 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
