Give the conclusion. Reject the null since the test statistic is in the rejection and the p- value is larger than the significance. Reject the null since the test statistic is in the rejection region and the p-value is smaller than the significance Fail to reject the null since the test statistic is not in the rejection region and the p-value is larger than the significance O Fail to reject the null since the test statistic is not in the rejection region and the p-value is smaller than the significance.
