A medical researcher wants to know whether a new exercise regimen has an effect on the pulse rate of women between 75 and 80 years old. She selects, at random, 12 such women and measures their pulse rate both before and after a 2-month period of the regimen. The accompanying table shows the before and after measurements. Use a one-tailed Wilcoxon Signed-Rank Test at alpha=0.05

H :Themedian pulse rateis the same before and after the regime 0

e) Find the value of the test statistic
f) Find the critical value ( from table 8)
g) State the statistical decision
h) State the decision in term of the problem

(Hint: Take advantage of the given columns for computations)
