A physical therapist wants to know whether a new exercise regimen has an effect on the pulse rate of women between 75 and 80 years old. He selects, at random, 12 such women and measures the pulse rate both before and after a 2-month period on the regimen. The pulse rates for these women with the first number the “before” rate and the second number the “after” rate are : (75, 71), (81,83), (74,70), (75,60), (70,75), (74,67), (82,85), (64,65), (79,69), (83,71), (73,65), (82,76). Conducting a Wilcoxon signed-rank test to determine if the median pulse rate is higher after the regimen. What is the test statistic?
