zachary completes a hypothesis test and finds that he rejects the null hypothesis. which statement gives a reason for rejecting the null hypothesis? the z - statistic is less than 0. the z - statistic lies in the critical region. the z - statistic lies outside the critical region. the z - statistic is greater than 0.

Answer

Brief Explanations:

In hypothesis - testing with z - statistics, if the z - statistic lies in the critical region, we reject the null hypothesis. A z - statistic less than 0 or greater than 0 does not necessarily mean we reject the null. And if the z - statistic lies outside the critical region, we fail to reject the null.

Answer:

B. The z - statistic lies in the critical region.
