The clinical testing of drugs involves many factors. For example, patients that have been given placebos, which are harmless compounds that have no effect on the patient, often will still report that they feel better. Assume that in a study of 500 random subjects conducted by the Poppins Sucre Drug Company, the percentage of patients reporting improvement when given a placebo was 37%. What confidence interval should be used to determine what percent of patients actually experience the placebo effect? One sample t-interval on the mean One sample z-interval on the proportion
