选项:
A.
B.
C.
解释:
你好,这道题应该A和C都是正确的吧?谢谢
NO.PZ2018062016000131 问题如下 In the steps of hypothesis testing, whiof the following scriptions on the statistically significant result is most accurate? A.When we test the null hypothesis, the absolute value of the test statistic is less extreme ththe absolute value of the criticvalue B.When we accept the null hypothesis, we cget a statistically significant result. C.When we rejethe null hypothesis, the result is statistically significant. C is correct. 当计算出来的检验统计量的绝对值大于临界值(criticvalue)的绝对值时,拒绝原假设,并简称为statistically significant B为什么不对呢?

C.When we rejethe null hypothesis, the result is statistically significant. C is correct. 当计算出来的检验统计量的绝对值大于临界值(criticvalue)的绝对值时,拒绝原假设,并简称为statistically significant A的意思不就是当测试值小于关键值的时候,我们要接受原假设吗?A为什么不对呢?

请问A错在哪?是不是错在当我们test,可能有两个结果(大于或小于临界值,并不一定像说的小于)? 另外请问given value一定指临界点吗?如果given value指临界值,是有可能正有可能负还是指绝对值?
