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.

2 = the claim shoud be rejeted.

The z-statistic lies in the critical region

Step-by-step explanation:

When a hypothesis test is performed, the decision to reject or not reject the null hypothesis is made on basis of following observations:

If the z-statistic falls in the critical or rejection region, there is enough evidence to reject the Null Hypothesis If the z-statistic falls outside the critical or rejection region, there is not enough evidence to reject the Null Hypothesis.

In the given statement Zachary rejects the Null Hypothesis, this means the z-statistic she calculated must have been inside the critical or rejection region. Hence the correct answer would be:

The z-statistic lies in the critical region
