What is the probability that a salesperson selected at random will have average sales ability and good potential for advancement?

0.09
None of these answers
0.12
0.525
0.30

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.

QUESTION: 735

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?

0.250.
0.234.
0.227.
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.

QUESTION: 736

A random variable, X, has a mean of 10 and a standard deviation of 15. Another random variable, Y, is defined by Y = 2X + 3. Then, which of the following is/are true? I. The mean of Y is 33. II. The variance of Y is 30. III. The standard deviation of Y is 33. IV. X and Y are perfectly correlated.

II and IV
I, II and IV
II only
III and IV
IV only
III only
I only

Answer(s): E

Explanation:

The mean of Y is 2*10 + 3 = 23. The standard deviation of Y is 2*15 = 30. Its variance is then equal to 30^2 = 900. Finally, since Y is a linear multiple of X, X and Y are perfectly correlated (positively, in this case)
