问题如下:
The following table shows the significance level (α) and the p-value for three hypothesis tests.
The evidence for rejecting H0 is strongest for:
选项:
A.Test 1.
B.Test 2.
C.Test 3.
解释:
C is correct.
The p-value is the smallest level of significance (α) at which the null hypothesis can be rejected. If the p-value is less than α, the null can be rejected. The smaller the p-value, the stronger the evidence is against the null hypothesis and in favor of the alternative hypothesis. Thus, the evidence for rejecting the null is strongest for Test 3.
老师,关于P-VALUE是通过样本统计量公式得出,算的是面积。但是在建设检验的步骤2,样本统计量算的是分割点,然后和显著性水平比较。 为什么同样公式,一个算出来的是面积,一个算出来的是分割点?
