题目
Which of the following represents a correct statement about the p-value?
选项
A.The p-value offers less precise information than does the rejection points approach.
B.A larger p-value provides stronger evidence in support of the alternative hypothesis.
C.A p-value less than the specified level of significance leads to rejection of the null hypothesis.
答案
C
解析
： C is correct. The p-value is the smallest level of significance at which the null hypothesis can be rejected for a given value of the test statistic. The null hypothesis is rejected when the p-value is less than the specified significance level. ： C正确。 当给定检验统计量值，p值是最小可以拒绝原假设的显著性水平。当p值小于指定的显著性水平时，拒绝原假设。
