Migraine and Acupuncture: A migraine is aparticularly painful type of headache, which patientssometimes wish to treat with acupuncture. Todetermine whether acupuncture relieves migrainepain, researchers conducted a randomized controlledstudy where 151 patients diagnosed with migraineheadaches were randomly assigned to one of twogroups: treatment or control. 70 patients in thetreatment group received acupuncture that isspecifically designed to treat migraines. 81 patients inthe control group received placebo acupuncture(needle insertion at non-acupoint locations). 24 hoursafter patients received acupuncture, they were askedthey were pain free. Results are summarized in thecontingency table below. Test to see if migraine painrelief is dependent on receiving acupuncture.

Is the average time to complete an obstacle course longer when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye.

A certain drug is used to treat asthma. In a clinical trial of the drug, 27 of 279 treated subjects experienced headaches (based on data from the manufacturer). The accompanying calculator display shows results from a test of the claim that less than 9% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a 0.01 significance level to complete parts (a) through (e) below. 1-PropZTest prop <0.09. z = 0.395382781 p=0.6537197926 p= 0.0967741935 =279
