weston completed a hypothesis test and found that he could not reject the null hypothesis. which of the following is a valid reason for his conclusion?\no the z - statistic is less than 0.\no the z - statistic lies in the critical region.\no the z - statistic is greater than 0.\no the z - statistic lies outside the critical region.
Answer
Brief Explanations:
In hypothesis - testing, if the z - statistic lies outside the critical region, we fail to reject the null hypothesis. If it lies in the critical region, we reject the null hypothesis. The sign of the z - statistic (less than 0 or greater than 0) alone does not determine whether we reject or fail to reject the null hypothesis.
Answer:
The z - statistic lies outside the critical region.
