Question:

In Chapter 12 we did this exercise assuming that the populations were normally distributed and that the population variances were equal. Assume that this is not the case. Using the Kruskal-Wallis test, is the outcome affected? Do you think unemployment benefits are normally distributed? Test for a difference in means at Î± = 0.05.

a. State the hypotheses and identify the claim.
b. Find the critical value.
c. Compute the test value.
d. Make the decision.
e. Summarize the results.
Use the traditional method of hypothesis testing unless otherwise specified.
