To evaluate the effect of a treatment, a sample of n= 8 is obtained from a population with a mean of µ = 40, and the %| treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M= 35. a. If the sample variance is s = 32, are the %| data sufficient to conclude that the treatment has a significant effect using a two-tailed test with a = .05? b. If the sample variance is s² = 72, are the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with a = .05? c. Comparing your answer for parts a and b, how does the variability of the scores in the sample influence the outcome of a hypothesis test?
