StatisticsStatistics for The Behavioral Sciences (MindTap Course List)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 2 = 32 , are the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with α = .05 ? b. If the sample variance is s 2 = 72 , are the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with α = .05 ? c. Comparing your answer for pans a and b, how does the variability of the scores in the sample influence the outcome of a hypothesis test?BuyFind*arrow_forward*
