Step-by-step explanation:

The test statistic is 19.1 - 18 V20 = 3.08 • The critical value is 2.1 = 1.28. Select two responses below.

= x Statistics - 4 hours & Select all that apply Reject At the 10 significance level, the data provide sufficient evidence to conclude that the mean commission is more than Fail to reject At the 10 significance level, the test results are not statistically significant and at best, provide weak evidence against the null hypothesis. The test statistic falls within the rejection region. The test statistics is NOT in the rejection region.
