To evaluate the effect of a treatment, a sample is obtained from a population with a mean of 30, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M = 31.3 with a standard deviation of s = 3. A. 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 α = .05? B. If the sample consists of n = 36 individuals, are the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with α = .05? C. Comparing your answers for a and b how does the size of the sample influence the outcome of the hypothesis test?
