A study is run to evaluate the effectiveness of an exercise program in reducing systolic
blood pressure in patients with pre-hypertension (defined as a systolic blood pressure
between 120-139 mmHg or a diastolic blood pressure between 80-89 mmHg). A total of
15 patients with pre-hypertension enroll in the study, and their systolic blood pressures
are measured. Each patient then participates in an exercise training program where they
learn proper techniques and execution of a series of exercises. Patients are instructed to
do the exercise program 3 times per week for 6 weeks. After 6 weeks, systolic blood
pressures are again measured.
What type of nonparametric test should be used to evaluate the effectiveness of an exercise program in reducing systolic blood pressure?
