Suppose that a placebo gives headache relief to 15% of patients who take it. A drug company tests a new drug using a sample of 1,000 people. They find that the new drug gives relief to a higher proportion of people, and the difference is statistically significant. Which of the following best describes how we should interpret these results? A., Because of the large size of the sample, these results are strong evidence that the new drug will help a much larger proportion of population. B. With a large sample, statistically significant results suggest a large improvement over the placebo. C. With a large sample, statistically significant results may actually be only a small improvement over the placebo. D. Regardless of the sample size, a statistically significant result means there is a meaningful difference in headache relief..
