ra=? rb= 20.0%
standard deviation=? standard deviation= 25.7%

a. The expected return for security rb= 20% and standard deviation- 25.7%. Find expected return and standard deviation for security A
b. find the value of wa that produces the minimum risk portfolio. Assume pab= -0.5 for parts b and c

c. Construct a table giving expected returns and standard deviations for portfolios with wa= 1.00, 0.75, 0.50, 0.25, 0.0 and the minimum risk value of A.

D. Graph the feasible set of portfolios and identify the efficient frontier of the feasible set.
