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.
