Each year a market research company surveys new car owners 90 days after they purchase their cars. This data is used to rate auto brands (such as Toyota and Ford) on quality and customer satisfaction. Suppose the following were the quality rating and satisfaction scores for 30 brands sold in the United States. Brand Quality Rating Satisfaction Rating Acura 64 814 Audi 80 863 BMW 76 849 Buick 74 792 Cadillac 58 826 Chevrolet 64 791 Chrysler 58 783 Dodge 58 790 Fiat 38 763 Ford 66 789 GMC 60 791 Honda 71 783 Hyundai 70 804 Infiniti 63 826 Jeep 43 762 Kia 72 791 LandRover 55 848 Lexus 76 844 Lincoln 65 835 Mazda 74 790 Mercedes-Benz 67 842 MINI 68 795 Mitsubishi 51 748 Nissan 63 786 Porsche 76 882 Scion 65 779 Subaru 78 766 Toyota 72 783 Volkswagen 67 796 Volvo 69 812 Calculate the value of the correlation coefficient. (Round your answer to four decimal places.)
