In a nondirectional one-sample t test, the null hypothesis states that the population mean is equal to a specified value, while the alternative hypothesis states that the population mean is not equal to the specified value (i.e. it could be larger or smaller). Therefore, we need to consider both tails of the sampling distribution of t as potential areas of rejection, depending on the direction of the difference between the sample mean and the specified value. Thus, the rejection region is located in both tails.
