A survey was recently conducted in which random samples of car owners of Chrysler, GM, and Ford cars were surveyed to determine their satisfaction. Each owner was asked to rate overall satisfaction on a scale of 1 (poor) to 1000 (excellent). The following data were recorded: If the analysts are not willing to assume that the population ratings are normally distributed and will use the Kruskal-Wallis test to determine if the three companies have different median ratings, what is the appropriate critical value if the test is to be conducted using an alpha = .05 level?
A) = 5.05
B) χ2 = 5.99
C) χ2 = 24.99
D) = 3.67
