A migraine is a particularly painful type of headache, which patients sometimes wish to treat with acupuncture. To determine whether acupuncture relieves migraine pain, researchers conducted a randomized controlled study where 89 females diagnosed with migraine headaches were randomly assigned to one of two groups: treatment or control. 43 patients in the treatment group received acupuncture that is specifically designed to treat migraines. 46 patients in the control group received placebo acupuncture (needle insertion at non-acupoint locations). 24 hours after patients received acupuncture, they were asked if they were pain free. Results are summarized in the contingency table below (Allais, 2011). (round answers to 2 decimal places) Pain Free: Pain Free: Total Yes No Treatment 10 33 43 Control 2 44 46 Total 12 77 89 d) Do the data provide convincing evidence that there is a real pain reduction for those patients in the treatment group? Or do you think that the observed difference might just be due to chance? Olt is impossible to tell merely by comparing the sample proportions because the difference could be the result of random error in our sample OYes, 23% is much higher than 4%

To determine whether acupuncture relieves migraine
pain, researchers conducted a randomized controlled
study where 89 females diagnosed with migraine
headaches were randomly assigned to one of two groups:
treatment or control. 43 patients in the treatment group
received acupuncture that is specifically designed to treat
migraines. 46 patients in the control group received
placebo acupuncture (needle insertion at non-acupoint
locations). 24 hours after patients received acupuncture,
they were asked if they were pain free. Results are
summarized in the contingency table below (Allais,
2011).
