Condé Nast Traveler magazine conducts an annual survey of its readers in order to rate the top 80 cruise ships in the world (Condé Nast Traveler, February 2008). With 100 the highest possible rating, the overall ratings for a sample of ships from the Holland America, Princess, and Royal Caribbean cruise lines are shown. Use the Kruskal-Wallis test with α = .05 to determine whether the overall ratings among the three cruise lines differ significantly. What is your conclusion?
