问题如下：
Which of the following statements about null hypothesis is least likely correct
选项：
A.
For sample statistic
B.
The fact we suspect and want to reject
C.
For population parameter
解释：
A is correct. By definition, null hypothesis is the fact we suspect and want to reject, we used population parameter.
请问下设立原假设后，后续步骤都是针对样本进行统计，为何A会不正确呢？

提问请问老师A为什么不对？C不是应该是用的样本参数么？为何C是对的？谢谢
怎么会使用population parameter, 哪里搞混了?
