Xarelto is a drug that can be used as a blood thinner for patients who have a pulmonary embolism or other blood clotting condition. Researchers wanted to determine if there was a difference in blood viscosity (measured in mPA S) that might be attributed to the drug. In a study, a random sample of 7 patients who had a family history of blood clotting disorders were treated with Xarelto for two months. Their blood viscosity was measured before and after the treatment. The data are shown the table below: Blood Viscocity (mPA. S) Patient 1 2 3 4 5 6 7 y S Before 6.7 7.1 5.6 6.9 7.5 6.8 5.7 6.61 0.71 After 4.3 4.6 6.7 4.4 6.0 4.9 5.8 5.24 0.92 Difference After - Before -2.4 -2.5 1.1 -2.5 -1.5 -1.9 -0.1 -1.37 1.42
