问一道题:NO.PZ2018062016000134

问题如下:

The p-value can be described as:

选项:

A.

If the p-value offers less than the specified level of significance, we rejected the alternative hypothesis.

B.

The larger p-value, the stronger evidence in favor of the alternative hypothesis.

C.

A p-value is equal to the minimum value of the level of significance at which the null hypothesis can be rejected.

解释:

C is correct. The p-value is the smallest level of significance at which the null hypothesis can be rejected. If the p-value is less than our specified level of significance, we reject the null hypothesis. The smaller the p-value, the stronger the evidence against the null hypothesis and in favor of the alternative hypothesis.

为什么A错了呀老师,不是P value小于α,就应该拒绝吗?

同学你好,

P越小越拒绝的是“原假设”,非备择假设
