Statistics Hypothesis Test Outputs

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?
