Quizplus · Accepted Answer

The rejection region for an upper-tailed test is in the right tail of the distribution. Since the alternative hypothesis states that the population mean is greater than 6,700, we are interested in values of the test statistic that are sufficiently large to reject the null hypothesis in favor of the alternative. Therefore, we reject the null hypothesis if our test statistic falls in the upper tail of the distribution, which corresponds to large positive values.
