  1. A sample of n = 16 participants is obtained, and each person’s tolerance for pain is tested before and after a 50-minute session of aerobic exercise. On average, the pain tolerance for this sample is MD = 10.5 points higher after exercise than it was before. The SS the sample of the difference scores is SS = 960. Do the data indicate that exercise produces a significant increase in pain tolerance? Use a one-tailed test with α = .01.
