问一道题:NO.PZ2018062016000136

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 higer, 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.

According to the evidence of rejecting the null hypothesis,

题目这里的Ho是什么,

同学你好,

H0就是对应的原假设,原假设是根据研究需要建立的。

这里对应的原理是“p越小越拒绝”,p越小,就有更强的证据去拒绝原假设。
