4. Medical researchers conducted a study to determine whether treadmill exercise could improve the walking ability of patients suffering from claudication, which is pain caused by insufficient blood flow to the muscles of the legs. A sample of 48 patients walked on a treadmill for six minutes every day. After six months, the mean distance walked in six minutes was 348 meters, with a standard deviation of 80 meters. For a control group of 46 patients who did not walk on a treadmill, the mean distance was 309 meters with a standard deviation of 89 meters. a. Can you conclude that the mean distance walked for patients using a treadmill is greater than the mean for the controls? Use the a = 0.05 level of significance and assume that subjects were randomly assigned to either the control group or the test group
