Question

The article “Utility of Pretest Probability and Exercise Treadmill Test in Korean Women with Suspected Coronary Artery Disease” (Y. Kim, W. Shim, et al., Journal of Women's Health, 2015:617–622) 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 test results 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. Can you conclude that the mean peak systolic blood pressure differs between these two groups of women?
