A social skills training program was implemented with seven mildly challenged students in a study to determine whether the program caused improvements in pre/post measures and behavior ratings. For one such test, the pre- and posttest scores for the seven students are
given in the table:

a. Use a nonparametric test to determine whether there is a significant positive relationship between the pre- and posttest scores.
b. Do these results agree with the results of the parametric test in Exercise 12.54?
