1. expected return = 0.3*0.15 + 0.7*0.06 = 0.087
standard dev = 0.3*square root of 0.04 = 0.06
2. capital allocation line
3. 15 - 5/30 = 0.33
4.
std dev = 8.13%
5.
E. Cannot tell from the information given.
6. A. securities' returns are uncorrelated.
7. A. 0
8.
C. the portion of the investment opportunity set which includes the portfolios with the lowest standard deviation.
