) In a trial of 350 patients who received 10-mg doses of a drug daily, 49 reported headache as a side effect. Construct a 90% confidence interval for the population proportion of patients who receive the drug and report headache as a side effect.
1. Use Minitab to build the confidence interval or run the hypothesis test. Be sure to interpret the results using everyday language.
a.) In a trial of 350 patients who received 10-mg doses of a drug daily, 49 reported headache as a side effect. Construct a 90% confidence interval for the population proportion of patients who receive the drug and report headache as a side effect.
b.) The percentage of physicians who are women is 32.4%. In a survey of physicians employed by a large university health system, 50 out of 120 randomly selected physicians were women. At the 5% significance level, is there sufficient evidence to conclude that the proportion of women physicians at the university health system exceeds 32.4%?
