To compare the efficiency of three different pesticides for controlling pests, a random sampling of 21 plots were carried out. The number of insects’ eggs for each plot was recorded and presented in the table below. Pesticide A Pesticide B Pesticide C 68 80 70 64 88 80 75 75 80 79 84 82 60 89 95 62 91 64 80 77 92Use the Kruskal-Wallis test to see if there is a difference in the efficiency of the three different pesticides at 5% significance level.
