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.
