Question: The results of two repeated-measures studies are summarized as follows: The first study produces a sample with MD = 4 and s= 9, and the second study produces MD = 12 and s = 9. Assume n = 10 for both samples. In each case, the sample mean and sample
standard deviation should provide enough information for you to visualize (or sketch) the sample distribution.

a. For each sample, identify where a value of zero is located. (Is zero in the middle of the sample or is it an extreme, unrepresentative value for the sample?)

b. Assuming that the samples are representative of their populations, which of the two samples is more likely to have come from a population with a mean difference of \({{\mu }_{D}}\) = 0? (Which sample is more likely to accept a null hypothesis that \({{\mu }_{D}}\) = 0?)
