Question

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 362 meters, with a standard deviation of 104 meters. For a control group of 61 patients who did not walk on a treadmill, the mean distance was 326 meters with a standard deviation of 110 meters. Can you conclude that the mean distance walked for patients using a treadmill is greater than the mean for the controls? Let μ1 denote the mean distance walked for patients who used a treadmill. Use the =α0.05 level of significance and the TI-84 Plus calculator.
