-A medical researcher wishes to try three different techniques to lower the weight of obese patients. The subjects are randomly selected and assigned to one of three groups. Group 1 is given medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six weeks, the reduction in each subject's weight (in pounds) is recorded. Use the Kruskal-Wallis test to test the hypothesis that there is no difference in the distribution of the populations. Use $\alpha = 0.05$ .
$\begin{array}{c|c|c}\text { Group 1 } & \text { Group 2 } & \text { Group 3 } \\\hline 13 & 10 & 8 \\14 & 7 & 14 \\11 & 4 & 6 \\17 & 5 & 10 \\15 & 6 & 11 \\10 & 2 & 6\end{array}$
