An article presents a study of health outcomes in women with symptoms of heart disease. In a sample of 100 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 220 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. Find a 95% confidence interval for the difference in mean systolic blood pressure between these two groups of women. (Round the final answers to three decimal places.)
