Consider the following table: Stock Fund Rate of Return Bond Fund Probability 0.10 0.20 0.40 0.30 Scenario Rate of Return Severe recession Mild recession Normal growth -34% -14% 19% 24% -13% 19% 12% -9% Boom 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 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
