p值是计算出来的吗

问题如下：

The following table shows the significance level (α) and the p-value for two hypothesis tests.

In which test should we reject the null hypothesis?

选项：

A.

Test 1 only

B.

Test 2 only

C.

Both Test 1 and Test 2

解释：

B 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 is rejected.

In Test 1, the p-value exceeds the level of significance, whereas in Test 2, the p-value is less than the level of significance.

p-value是可以拒绝原假设的最小显着性水平 (α)。

Test 1, p-value大于显著性水平；而在Test 2, p-value小于显著性水平，所以拒绝原假设。
