问题如下：
The following table shows a set of data usd for a statistical test.
Peter sets up a null hypothesis--- H0: μ≥8.5, which of the following statement is most appropriate to describe Peter's objective?
选项：
A.Peter believe that the population mean is greater than 8.5.
B.Peter believe that the population mean is less than 8.5.
C.Peter believe that the population mean is 8.5.
解释：
B is correct.
If someone wants to reject a hypothesis, then he or she will place it in the null hypothesis.
老师，这道题的答案我能理解。只是奇怪，题目中明明已经给出了总体均值，此时做原假设，是不是应该原假设=总体均值比较合理，题目中的原假设小于总体均值，似乎不合常理？
