Exercise 4. We draw 5, 5, 7 samples from 3 populations respectively. The results are 5, 4, 6, 4, 6 X1; ~ F₁. 7, 3, 5, 6, 5 X2j ~ F2. 2, 3, 3, 1, 2, 1, 1 X3j ~ F3. Check the claim that there is no difference in the three populations at significance level 0.01 using the Kruskal-Wallis test (using X² approximation).
