Ekin Running shoe designers wanted to test the wear in two different designs of running shoes. They chose a random sample of 6 amateur runners, and had them wear both designs of shoe until the shoe was no longer usable. Which shoe was worn first was randomly assigned. The length of wear for each design was recorded for each runner in weeks. Is there evidence of a difference, on average, in the wear time of the two designs?

Upload your work as a pdf/word file. For step 5, you need an output from both JMP and Excel. Snip both JMP and Excel outputs into your file. (Note: You do not need an output for CI, since it should be included in your JMP output for step 5. Also note that this table will paste nicely into Excel. Runner Design 1 Design 2 1 114 95 2 115 123 3 116 100 4 128 86 5 110 108 6 120 95 Make sure that you upload the correct file.
