Four independent random samples are given on the text website. Conduct a Kruskal-Wallis test to compare populations. Use a = 0.05.

Three independent random samples were obtained, and the data are given on the text website. Use the Kruskal-Wallis test with a = 0.05 to test the hypothesis that all three populations are identical.

The National Snow and Ice Data Center collects information on glaciers from around the world. Some of the parameters include the number of basins, the mean depth, and the primary class. A random sample of glaciers in Western Europe was obtained, and the total area (in square kilometers) of each was recorded.22 GLACIERS

a. Use the Kruskal-Wallis test with a = 0.05 to test the hypothesis that all four glacier-area populations are identical. Assume the underlying populations are continuous.

b. Interpret your results in part (a). Which region has on average the largest glaciers by area?
