Of 40 first-time buyers, 11 preferred European styling and 29 preferred Japanese styling. Of 60 repeat buyers, 43 prefer European styling and 17 preferred Japanese styling. (a) Set up a contingency table for these data. Buyers First-time Repeat Total European Xx^2 = Style Japanese Total (b) Test the hypothesis that buyer status (repeat versus first-time) and styling preference are independent at the .05 level of significance. What do you conclude? (Round your answer to 3 decimal places.) HO: independence.
