Consider the following table: Scenario Severe recession Mild recession Normal growth Boom Stock Fund Bond Fund Probability 0.10 Rate of Return -38% Rate of Return -11% 0.20 -18% 17% 0.40 0.30 23% 10% 28% -7% Required: a. 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 Answer is complete and correct. 10.2 % 551.96 b. Calculate the value of the covariance between the stock and bond funds. (Negative value should be indicated by a minus sign.
