1. 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 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. 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 M significance. 10.11.92 2 on 301:165-174

![14. 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 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. 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.
