Exercise: 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 72 patients walked on a treadmill for six minutes every day. After six months, the mean distance walked in six minutes was 347 meters, with a standard deviation of 79 meters. For a control group of 61 patients who did not walk on a treadmill, the mean distance was 307 meters with a standard deviation of 88 meters. Can you conclude that the mean distance walked for patients using a treadmill differs from the mean for the controls? Let μ, denote the mean distance walked for patients who used a treadmill and let μ₂ denote the mean distance walked for the controls. Use the a= 0.10 level of significance and the critical value method.
