Q: JoLynn Miller is a physical therapist at the local senior center. She has been testing a new procedure to improve leg strength that requires the patient to use weights to do repetitions using a new apparatus. JoLynn decides to test the effectiveness of the apparatus on two patients with similar mobility restrictions. The number of repetitions that each patient could do is recorded below. At the .05 significance level, is the number of repetitions for Patient A significantly less than Patient B?
