### Study on the Impact of Treadmill Exercise on Walking Ability in Patients

**Objective:** Medical researchers conducted a study to determine whether treadmill exercise could improve the walking ability of patients suffering from claudication, which is caused by insufficient blood flow to the muscles of the legs.

**Methodology:**
- **Sample Groups:**
  - 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 88 meters.
  - A control group of 46 patients who did not walk on a treadmill had a mean walking distance of 309 meters with a standard deviation of 89 meters.

**Analysis:**
- **Objective:** Can you conclude that the mean distance walked for patients using a treadmill is greater than the mean for the controls?
- **Significance Level:** Use the α = 0.05 level of significance.
- **Assumptions:** Assume that subjects were randomly assigned to either the control group or the test group.

The text set the stage for a statistical comparison between the treadmill group and the control group to determine the effectiveness of the treadmill exercise program on improving walking distances in patients. 

To conduct this analysis, one would likely perform a hypothesis test for the difference between two means, considering the provided means, standard deviations, and sample sizes. The α = 0.05 level of significance will determine the threshold for concluding whether there is a statistically significant difference between the two groups.
