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B这个suspect啥意思？是说H0是我怀疑并且想拒绝的假设吗？因为之前看到好像Ha也是我suspect的，就有点懵

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?
