Comparing the test statistic with the rejection region In a Two-Tailed Hypothesis test, the test statistic was found to be Z = - 1.37 The rejection region included values less than Zc = - 1.9 or greater than Zc = 1.90 Rejection Region Rejection Region Left side Right side -Zc 0 +Zc The conclusion would be to... O Reject the null hypothesis because the test statistic is NOT in the rejection region O Fail to reject the null hypothesis because the test statistic is in the rejection region O Fail to reject the null hypothesis because the test statistic is NOT in the rejection region O Reject the null hypothesis because the test statistic is in the rejection region O Accept the null hypothesis because the test statistic is NOT in the rejection region
