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 of81patients walked on a treadmill for six minutes every day. After six months, the mean distance walked in six minutes was485meters, with a standard deviation of113

meters. For a control group of84patients who did not walk on a treadmill, the mean distance was500meters with a standard deviation of127meters. Can you conclude that the mean distance walked for patients using a treadmill is less than the mean for the controls? Let1denote the mean distance walked for patients who used a treadmill.
