In a study of treatments for very painful "cluster" headaches, 149 patients were treated with oxygen and 157 other patients were given a placebo consisting of ordinary air. Among the 149 patients in
the oxygen treatment group, 117 were free from headaches 15 minutes after treatment. Among the 157 patients given the placebo, 38 were free from headaches 15 minutes after treatment. Use a
0.05 significance level to test the claim that the oxygen treatment is effective. Complete parts (a) through (c) below.
