Consider the following table

Stock Fund Bond Fund

Scenario Probability Rate of Return Rate of Return

Severe recession 0.10 ?30% ?11%

Mild recession 0.15 ?12% 8%

Normal growth 0.35 6% 2%

Boom 0.40 39% 5%

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.)

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.)
