The same social researcher as in Problem 38 then focuses on differences in livability by region. Selecting eight cities from each region of the country at random, he obtains the following rankings based on the magazine’s assessments.

Applying the Kruskal-Wallis test, determine whether there is a significant difference among the regions with respect to livability. Note that the magazine’s rankings should be re-ranked from 1 (most livable) to 32 (least livable) to reflect the order within the sample (for example, the sample’s most livable city at #5 should be ranked 1, and the sample’s least livable at #193 should be ranked 32).
