a.

Calculate the expected value of the portfolio return. (Round your answer to 2 decimal places.)

  Proportion of fund A =0.4

Proportion of fund B =1-0.4 =0.6

  Expected value = 0.4*12+0.6*7 = 9.00

  

b.

Calculate the standard deviation of the portfolio return. (Round your intermediate calculations to 4 decimal places and final answer to 2 decimal places.)

Portfolio Variance = w2A*?2(RA) + w2B*?2(RB) + 2*(wA)*(wB)*Cov(RA, RB)

Variance = 0.4^2*98+0.6^2*44 +2*0.4*0.6*33 = 47.36

standard deviation of the portfolio return = sqrt(47.36) =6.88
