Consider the following table:

		Stock Fund	Bond Fund
Scenario	Probability	Rate of Return	Rate of Return
Severe recession	0.05	27%	12%
Mild recession	0.25	7%	18%
Normal growth	0.40	12%	11%
Boom	0.30	17%	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.)

Mean return		6.80 %
Variance		146.76 %-Squared

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.)

Covariance ________ %-Squared
