Extracted text: In an experiment to determine which of the three different missile systems is preferable, the propellant burning rate is measured. The data, after coding, are given in the following table. Use the Kruskal-Wallis Test and a significance level of alpha a = 0.05 to test the hypothesis that the propellent burning rates are the same for the three missile systems. A В D Missile System 1 2 3 24 23.2 18.4 16.7 19.8 19.8 22.8 18.1 17.3 19.8 17.6 17.3 18.9 20.2 19.7 17.8 18.9 18.8 19.3
