6.6 Each of 12 patients went on the South Beach diet for 5 weeks. Their weights before and after the diet are listed here. Perform a paired t-test comparing before and after values. Analyze these data as if the values were not paired. How do the p-values compare? Note: If you want to make this problem easier, read in the data by subject, with the before and after values. If you would like a challenge, read in all of the before values (perhaps into an array) and then all the after values, and create the data set with each observation having a subject number and the before and after scores.
