单尾不是＜critical value接受原假设吗

  1. CFA I
  2. Quantitative

NO.PZ2018062016000123

问题如下：

Which of the following statements about one-side hypothesis test is most correct ?

选项：

A.

We reject the null only if the evidence indicates that the population parameter is smaller or larger than the critical value.

B.

Do not have Type I error.

C.

We reject the null only if the evidence indicates that the test statistic is greater than or less than the critical value.

解释：

C is correct. By definition, one-side hypothesis test also called one-tailed hypothesis test, which reject rule is reject the null only if the evidence indicates that the test statistic is greater than or less than the critical value.

选项C也没说绝对值啊

同学你好，

C选项的“ greater than or less than”描述对应的就是绝对值的情况。如果是正数的情况，就对应greater than；负数则为less than
