题目
The following table shows the significance level (α) and the p-value for two hypothesis tests.「huixue_img/importSubject/1564548697830854656.png」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
答案
B
解析
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.B是正确的。p值是可以拒绝原假设的最小显著性水平(α)。如果p值小于α,则拒绝空值。在测试1中,p值超过显著性水平,而在测试2中,p值低于显著性水平。
