In a clinical trial of 20922092 subjects treated with a certain drug, 2626 reported headaches. In a control group of 17551755 subjects given a placebo, 2424 reported headaches. Denoting the proportion of headaches in the treatment group by pt and denoting the proportion of headaches in the control (placebo) group by pc, the relative risk is pt/pc. The relative risk is a measure of the strength of the effect of the drug treatment. Another such measure is the odds ratio,...

In a clinical trial of a drug intended to help people stop smoking, 127 subjects were treated with the drug for 11 weeks, and 18 subjects experienced abdominal pain. If someone claims that more than 8% of the drug's users experience abdominal pain, that claim is supported with a hypothesis test conducted with a 0.05 significance level. Using 0.17 as an alternative value of p, the power of the test is 0.95. Interpret this value of the power of the...
