In an experiment to determine which of three different missile systems is preferable, the propellant burning rate is measuresd. The data after coding are given in the table. Use Kruskal-Wallis test (significance level of 0.01) to test the hypothesis that the propellant burning rates are same for three missile systems.

Missile system I 22.3 16.7 22.7 19.3 18.5
Missile system II 23.4 19.5 17.5 20.8 16.0 19.9
Missile system III 18.4 19.5 17.8 18.0 19.6 22.8 17.1
