Assume that you want to test the claim that the paired sample data below come from a population from which the mean difference is zero. Using JMP, compute the value of the appropriate test statistic. Do the data appear to come from a population where the mean difference is zero? X: 28 35 25 25 32 30 28 37 Y: 26 31 31 25 33 35 28 33 a. No b. O c. Yes d.
