Consider the following table:

Scenario	Probability	Stock Fund rate of return	Bond fund rate of return
Severe Recession	.05	-32%	-10%
Mild Recession	.25	-10%	6%
Normal Growth	.40	22%	10%
Boom	.30	37%	7%

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 4 decimal places.) Mean return %

Variance

b. 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 4 decimal places.)

Covariance
