p-value 、 α和critical value的关系是什么呀？

问题如下：

According to the evidence of rejecting the null hypothesis, which of the following statements is most accurate?(Assume that the level of significance is represented by α)

选项：

A.

When the p-value is lower than α, the p-value is higher, the evidence is stronger.

B.

When the p-value is higher than α, the p-value is lower, the evidence is stronger.

C.

When the p-value is lower than α, the p-value is lower, the evidence is stronger.

解释：

C is correct. The p-value is the smallest level of significance(α) at which the null hypothesis can be rejected for a given value of the test statistic. The p-value is lower, the evidence of rejecting the null hypothesisthe is stronger.
