a. A repeated-measures study with a sample of n = 9 participants produces a mean difference of
Question:
Use a two-tailed hypothesis test with a = .05 to determine whether it is likely that this sample came from a population with mD = 0.
b. Now assume that the sample mean difference is MD = 12, and once again visualize the sample distribution. Use a two-tailed hypothesis test with a = .05 to determine whether it is likely that this sample came from a population with mD = 0.
c. Explain how the size of the sample mean difference influences the likelihood of finding a significant mean difference.
