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