Refer to Data Set 21 in Appendix B. A desirable trait for a top-rate diamond is to be flawless. Clarity is a measure of this characteristic-with 1 being the best. At the 0.05 level, test the claim that the prices of diamonds are not the same for each of the four clarity values listed (2, 3, 4, and 5). Would you conclude that clarity is a major determinant of price? If you need more information to answer the question, explain.
Use the Kruskal-Wallis test.
