题目
Which of the following statements is correct with respect to the p-value?
选项
A.It is a less precise measure of test evidence than rejection points.
B.It is the largest level of significance at which the null hypothesis is rejected.
C.It can be compared directly with the level of significance in reaching test conclusions.
答案
C
解析
： C is correct. When directly comparing the p-value with the level of significance, it can be used as an alternative to using rejection points to reach conclusions on hypothesis tests. If the p-value is smaller than the specified level of significance, the null hypothesis is rejected. Otherwise, the null hypothesis is not rejected. ： C正确。 当直接比较p值与显著性水平时，它是一种替代方法，在假设检验中运用了拒绝点以便得出结论。如果p值小于指定的显著性水平，则拒绝原假设。否则，不拒绝原假设。
