Armstrong · Answer 1

One can reject the null hypothesis.

Step-by-step explanation:

This is a 2-sided hypothesis test since we have 2 critical values; - 1.96 and 1.96. The test is usually to compute the test statistic then reject the null hypothesis if the test statistic lies in the critical/rejection region.

In our case, we reject the null hypothesis since 2.1 lies to the right of 1.96 which forms a part of the critical region
