The article “Utility of Pretest Probability and Exercise Treadmill Test in Korean Women with Suspected Coronary Artery Disease” presents a study of health outcomes in women with symptoms of heart disease. In a sample of 110 women whose test results suggested the presence of coronary artery disease, the mean peak systolic blood pressure was 169.9 mmHg, with a standard deviation of 24.8 mmHg. In a sample of 225 women whose testresults suggested an absence of coronary artery disease, the mean peak systolic blood pressure was 163.3 mmHg, with a standard deviation of 25.8 mmHg. Find a 95% confidence interval for the difference in systolic blood pressure between these two groups of women.
