Each owner was asked to rate overall satisfaction on a scale of 1 (poor) to 1000 (excellent). The following data were recorded. Chrysler GM Ford 650 100 700 700 800 750 500 500 650 800 400 800 900 600 900 750 900 700 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? O A. x2 = 3.67 O B. x2 = 5.99 O C. x2 = 5.05 O D. X2 = 24.99 Click to select your answer. ?
