  1. CFA I
  2. Quantitative

NO.PZ2018062016000120

问题如下：

which of the following statement is most likely correct?

选项：

A.
Reject the null hypothesis if the
test statistic
＞
critical value
B.
Accept the null hypothesis if the
test statistic
＞
critical value
C.
Reject the null hypothesis if the
test statistic
＜
critical value

解释：

A is correct, according to the decision rule, reject the null hypothesis if the |test statistic| ＞|critical value|, and we can only say cannot reject the null hypothesis.

解析是不是有问题？T大于C时，拒绝原假设，怎么又是只能说不能拒绝原假设？

同学你好，

这两句不是递进关系。

后面半句是独立的，意思是我们只能说“不能拒绝”原假设，不能说“接受”原假设。并不是顺着前半截下来的。
