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?\nthe z - statistic is less than 0.\nthe z - statistic lies in the critical region.\nthe z - statistic is greater than 0.\nthe z - statistic lies outside the critical region.
Answer
Brief Explanations:
In hypothesis - testing, if the test - statistic (in this case, the z - statistic) lies outside the critical region, we fail to reject the null hypothesis. If it lies within the critical region, we reject the null hypothesis. The sign of the z - statistic (less than 0 or greater than 0) alone is not the determining factor for rejecting or not rejecting the null hypothesis.
Answer:
The z - statistic lies outside the critical region.
