Type 1 diabetes, medical graduate students subdivided the United States into four
study regions (Northeast, Southeast, Southwest, and Northwest). The students
randomly selected seven patients per region and recorded the number of times on
a randomly selected day that each patient used insulin shots to regulate blood
sugar levels. Use the Kruskal-Wallis Test at a .05 significance level to test the claim
that the regions have samples that come from populations with equal medians of
number of insulin shots.
