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?
