这个题的C 答案不对吗?

NO.PZ2018062016000124

问题如下:

Which of the following descriptions on a two-tailed hypothesis test is least correct?

选项:

A.

A two-tailed test is less directive than a one-tailed test. 

B.

The alternative hypotheses of one-tailed tests has less impacts on the researcher's beliefs than the alternative hypotheses of two-tailed tests. 

C.

Under the same significance level, the absolute value of two-tailed test's rejection points is larger than the one of one-tailed test.

解释:

B is correct. A two-tailed test is a “not equal to” alternative hypothesis, while a one-tailed test is a “greater than” or “less than” alternative hypothesis. “greater than” or “less than” alternative hypotheses reflect the beliefs of the researcher more strongly than a "not equal to" alternative hypothesis.

我感觉C 答案也是对的

B的翻译是不是单尾实验对实验者的信仰影响小于双尾实验,那意思就是在单尾实验中实验者更确定自己的偏向对吧?另外题目中的least correct是最不正确的意思对吗?两者是否有冲突?
