zachary completes a hypothesis test and finds that he rejects the null hypothesis. which statement gives a reason for rejecting the null hypothesis?\nthe z - statistic is less than 0.\nthe z - statistic lies in the critical region.\nthe z - statistic lies outside the critical region.\nthe z - statistic is greater than 0.
Answer
Brief Explanations:
In hypothesis - testing, the null hypothesis is rejected when the test - statistic (in this case, the z - statistic) lies in the critical region. The sign of the z - statistic (less than 0 or greater than 0) alone is not the determining factor for rejecting the null hypothesis. If the z - statistic is outside the critical region, the null hypothesis is not rejected.
Answer:
The z - statistic lies in the critical region.
