Consider the following table: Scenario Severe recession Mild recession Normal growth Boom Probability 0.10 0.20 0.30 0 40 Stock Fund 34% 21% Bond Fun Rate of Return -9% 5% 9% -6% Rate of Return -20 0% 36% a. Calculate the values of mean return and variance for the stock fund. (Do not round intermediate calculations. Round place and "Variance" to 4 decimal places.) Mean return" value to 1 dea Mean return Squared Variance stock and bond funds. (Negative value should be indicated by a minus sign. Do not round interm b. Calculate the value of the covariance between the calculations. Round your answer to 4 decimal places.) Covariance %-Squared
