Question

In a test of running shoes, French sporting goods manufacturer Mostelle randomly chose six amateur runners to test two of its new shoe designs. The order in which each runner tested the shoes was randomly determined. The table shows how long the test shoes lasted before they were no longer usable. Treating each runner as a matched pair of subjects and assuming that all necessary population conditions are satisfied, build a 90% confidence interval estimate of the difference in average wear for the populations represented.
