问题如下：
which of the following statement is most likely correct?
选项：
A.Reject the null hypothesis if the 
Accept the null hypothesis if the
Reject the null hypothesis if the 
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.
如果test statistic>critical value，不是会落在接受域里面吗，应该是大于右尾critical value或小于左尾critical value才落在拒绝域里面吧？
