Consider the following table:

		Stock Fund	Bond Fund
Scenario	Probability	Rate of Return	Rate of Return
Severe recession	0.10	43%	12%
Mild recession	0.20	17%	12%
Normal growth	0.30	17%	6%
Boom	0.40	31%	4%

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
