For #39-45: A researcher would like to determine whether Model A for shoe orthotics or Model B for
shoe orthotics is better at reducing foot pain in an elderly population. He draws a sample of 8 people
from a podiatry practice to try out both models in a repeated-measures design. The participants will
wear each model of show orthotics for 8 hours during a day and then rate their pain. The dependent
variable is pain rating on a scale of 1-10, with 1 being no pain and 10 being excruciating pain. The data in
