A researcher wants to know whether a pharmaceutical intervention to reduce stress is working. N = 25 individuals are randomly assigned to receive the drug of interest and have a sample mean (M) of 76.4, whereas N = 29 individuals are randomly assigned to receive a placebo pill and have a sample mean of 83.0.

Independent-Samples t-Test In a research project, researchers track the health and cognitive functions of the elderly in the community. To examine any possible gender differences in their sample, they want to see if the females and the males differ significantly on the education level (number of years of formal schooling). The researchers are not predicting any direction in the possible gender differences so the hypotheses should be non-directional. They would like to run a two-tailed test with α = .10....
