Questions 1:
An investor purchases 100 shares of stock at $40 per share. The investor holds the shares for exactly one year and then sells all of them at $41.50 per share. On the date of sale, the investor receives dividends totaling $200. The holding period return (HPR) on the investment is closest to:
A 、8.75%.
B、 3.75%.
C、 8.43%.
Questions 2:
When testing a hypothesis, the power of a test is best described as the:
A 、same as the level of significance of the test.
B、 probability of rejecting a true null hypothesis.
C、 probability of correctly rejecting the null hypothesis.
A is correct. HPR = (P1 – P0 + D1)/P0. In this problem: (41.50 – 40 + 2)/40 = 8.75%.
B is incorrect; it is calculated as (41.50 – 40)/40 = 3.75% (ignores dividends).
C is incorrect; it is calculated as (41.50 – 40 + 2)/41.50 = 8.43% (wrong denominator)
C is correct. The power of a test is the probability of correctly rejecting the null hypothesis—that is, the probability of rejecting the null when it is false.
A is incorrect because this is the definition of Type I error.
B is incorrect because this is in fact a Type I error.
成功=时间+方法，自制力是这个等式的保障。世上无天才，高手都是来自刻苦的练习。而人们经常只看到“牛人”闪耀的成绩，其成绩背后无比寂寞的勤奋。小编相信，每天都在勤奋练习，即使是一点点的进步，大家一定可以成为人人称赞的“牛人”。更多CFA考试资讯，点击了解>
