After reading an article about the benefits of acupuncture, a researcher decides to conduct an experiment to determine if acupuncture has an effect on back pain. The researcher recruits 11 people with chronic back pain to participate in a study. Each participant rates his or her back pain prior to the acupuncture and following the acupuncture. Ratings are made on a 10-point scale with higher numbers indicating greater back pain. Test the researcher's assumption using an alpha level
