To evaluate the effect of a treatment, a sample is ob- tained from a population with a mean of u= 40, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M =44.5 with a variance of s2 = 36. If the sample consists of n = 4 individuals, 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 consists of n = 16 individuals, are the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with a = .05? c. Comparing your answers for parts a and b, how does the size of the sample influence the outcome of a hypothesis test?
