In a one-tailed test of hypothesis, the researcher has a specific direction in mind for the outcome. Therefore, the critical region, which is the area of extreme values that would support rejecting the null hypothesis, should be placed entirely in either the upper or lower tail of the sampling distribution. This is because the null hypothesis is assumed to be true unless evidence suggests otherwise, and the researcher is only interested in rejecting the null hypothesis in one direction. The sample mean, population distribution, and Z-score are not directly applicable in determining the critical region for a one-tailed test.
