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 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 blood pressure is recorded. Use the Kruskal-Wallis test to find the critical value to test the claim that there is no difference in the distribution of the populations. Use a = 0.05. Group 1 Group 2 Group 3 16 13 11 17 10 17 14 7 20 8 13 18 9. 14 13 ..... O A. 3.195 O B. 1.960 O C. 5.991 O D. 4.153 9.
