Description

Following are data on price, curb weight, horsepower, time to go from 0 to 60 miles per hour, and the speed at 1/4 mile for 16 sports and gt cars. Sports & GT Car/ Price (\$1000s)/ Curb Weight (lb.)/ Horsepower /0-60 mph (seconds) /Speed at 1/4 mile (mph) Acura Integra Type R 25.035 2577 195 7 90.7 Acura NSX-T 93.758 3066 290 5 108 BMW Z3 2.8 40.900 2844 189 6.6 93.2 Chevrolet Camaro Z28 24.865 3439 305 5.4 103.2 Chevrolet Corvette 50.144 3246 345 5.2 102.1 Dodge Viper RT/10 69.742 3319 450 4.4 116.2 Ford Mustang GT 23.200 3227 225 6.8 91.7 Honda Prelude Type SH 26.382 3042 195 7.7 89.7 Mercedes-Benz CLK320 44.988 3040 205 7.2 93 Mercedes-Benz SLK230 42.762 3025 185 6.6 92.3 Mitsubishi 3000GT VR-4 47.518 3737 320 5.7 99 Nissan 240SX SE 25.066 2862 155 9.1 84.6 Pontiac Firebird Trans Am 27.770 3455 305 5.4 103.2 Porsche Boxster 45.560 2822 201 6.1 93.2 Toyota Supra Turbo 40.989 3505 320 5.3 105 Volvo C70 41.120 3285 236 6.3 97 Develop a regression model with curb weight, horsepower, time from 0-60 mph, and the speed at 1/4 mile as 4 different independent variables to predict the car price. Typically, you should keep only significant variables in your final estimated regression model. That is, if you find statistically insignificant variables, you should remove them from the model and then re-run the model again (one at a time). However, for this particular homework problem, please keep all 4 independent variables in the final estimated equation even if some of the independent variables might not be statistically significant at the .10 alpha level. a. Please specify the regression model?b. At a .10 level of significance, please report your conclusions related to the hypotheses specified in part (a). c. Again, please focus your attention on the estimated regression equation (with one dependent variable and four independent variables). Please predict the price of a sports car that takes only 7 seconds from 0 to 60 mph, along with the following features: 2,850 lbs, 200 horsepower, 100 mph 1/4 mile. In addition, please report the 95% prediction interval related to the estimated price.
