A 、7.97%.

B、 8.15%.

A 、0.01.

B 、0.05.

C 、0.10.

View answer resolution

【Answer to question 1】B

【analysis】

B is correct. The money-weighted rate of return is the internal rate of return (IRR) of the cash flows associated with the investment. The following figure represents the timeline for the problem:

quantity exercise:null hypothesis

A is incorrect. It adds all three dividends together and (incorrectly) calculates the HPR of the investment as (2 + 2.25 + 102.75)/85 = 1.25882353. Then the third root of this number is taken and 1 is subtracted. The result is 7.97%.

C is incorrect. It is calculated by subtracting 1 from 1.25882353 (see Justification A) and dividing the remainder by 3. The result is 8.63%.

【Answer to question 2】A

【analysis】

A is correct. By the definition of p-value, 0.03 is the smallest level of significance at which the null hypothesis can be rejected. An analyst cannot reject the null hypothesis at the 0.01 significance level.

B is incorrect. As explained in choice A

C is incorrect. As explained in choice A.
