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 all 33 brands sold in the United States. Brand Quality Rating Satisfaction Rating Acura 86 822 Audi 111 832 BMW 113 845 Buick 114 802 Cadillac 111 818 Chevrolet 111 789 Chrysler 122 748 Dodge 130 751 Ford 93 794 GMC 126 792 Honda 95 766 Hyundai 102 760 Infiniti 107 805 Jaguar 130 854 Jeep 129 727 Kia 126 761 Land Rover 170 836 Lexus 88 822 Lincoln 106 820 Mazda 114 774 Mercedes-Benz 87 837 Mercury 113 769 Mini Cooper 133 815 Mitsubishi 146 767 Nissan 111 763 Porsche 83 882 Ram 110 780 Scion 114 764 Subaru 121 755 Suzuki 122 750 Toyota 117 740 Volkswagen 135 797 Volvo 109 795 Compute the value of the correlation coefficient.

The Toyota Camry is one of the best-selling cars in North America. The cost of a previously owned Camry depends on many factors, including the model year, mileage, and To investigate the relationship between the car’s mileage and the sales price for Camrys, the following data show the mileage and sale price for 19 sales (PriceHub Web site, February 24, 2012). Miles (1000s) Price ($1,000s) 22 16.2 29 16.0 36 13.8 47 11.5 63 12.5 77 12.9 73 11.2 87 13.0 92 11.8 101 10.5 110 8.3 28 12.5 59 11.1 68 15.0 68 12.2 91 13.0 42 15.6 65 12.7 110 8.3 Develop an estimated regression equation showing how price is related to miles. What is the estimated regression model? Test whether each of the regression parameters b0 and b1 is equal to zero at a 0.01 level of significance. What are the correct interpretations of the estimated regression parameters? Are these interpretations reasonable? How much of the variation in the sample values of price does the model estimated in part b explain?
