Consider the following table:

Scenario Probability Stock Rate of ReturnRate Bond Fund Rate if Return

1. Severe recession 0.10 44% 11%
2. Mild recession 0.20 24% 17%
3. Normal growth 0.40 29% 10%
4. Boom 0.30 34% 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 2 decimal places.)

Mean return 12.6 %

Variance _________%-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
