To evaluate the effect of a treatment, a sample of n = 6 is obtained from a population with a mean of µ = 80, and the treatment is administered to the individuals in the sample. After the treatment, the sample mean is found to be M = 72. a. If the sample variance is s2 = 54, 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 s2 = 150, are the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with α=.05?
