Answer(s): F

  1. 0.09
  2. None of these answers
  3. 0.12
  4. 0.525

Answer(s): C

Explanation:

Prob. of selecting a person with average sales ability: (45 + 60 + 45)/500 = 3/10. Prob. of selecting good potential amongst those with average sales ability: 60/150. Therefore: 3/10*6/15 = 0.12.



You are given a risk-free rate of 3% per year, a portfolio return of 8% per year, and a standard deviation of portfolio return of 22% per year. What is the Sharpe measure of risk-adjusted performance?

  1. 0.250.
  2. 0.234.
  3. 0.227.
  4. 0.222.

Answer(s): C

Explanation:

The Sharpe measure of risk-adjusted performance is equal to (rbar_p - rbar_f)/sigma_p, where rbar_p is the mean portfolio return, rbar_f is the mean risk-free return, and sigma_p is the standard deviation of portfolio return. In our case, we have (8% - 3%) / 22% = 5/22 = 0.227.
