Use the following sample data to answer the next questions. For a study on 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. Number of times patients used insulin shots to regulate blood sugar levels -Identify the null hypothesis and alternative hypothesis.
