10. A measure of the right atrial pressure (mm Hg) was made for cardiac patients who were given Captopril and for those given Nitroprusside. The random sample of 21 patients' given Captopril had a right atrial pressure of 7.8 mm Hg and a standard deviation of 1.44 mm Hg. For the 21 patients given Nitroprusside, the mean right atrial pressure was 6.6 mm Hg, and the standard deviation was 1.6 mm Hg. Test the hypothesis at the 0.01 level that there's no difference in the population mean right atrial pressure between the two groups.
