Consider the following table:

			Stock Fund			Bond Fund
Scenario	Probability		Rate of Return			Rate of Return
Severe recession	0.10		39	%		12	%
Mild recession	0.20		19	%		18	%
Normal growth	0.40		24	%		11	%
Boom	0.30		29	%		8	%

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.) 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 2 decimal places.)
