Does the asking price of a new car vary according to whether the dealership is in a small town, a city, or a suburban area? To test this question, a researcher randomly selects dealerships selling Buicks in the state of Illinois. The researcher goes to these dealerships posing as a prospective buyer and makes a serious inquiry as to the asking price of a new Buick Regal sedan (each having the same equipment).
The following data represent the results of this sample. Is there a significant difference between prices according to the area in which the dealership is located? Use the Kruskal-Wallis test and α =.05.
