Perhaps an easier way to see the major difference in the two analysis approaches for these data is by computing 95% confidence intervals for the mean difference. a. Compute the 95% confidence interval using the two-sample t confidence interval. b. Compute the 95% confidence interval using the matched pairs t confidence interval. c. Compare the estimates (that is, the centers of the intervals) and margins of error. What is the major difference between the two approaches for these data
