Question

A corporation has asked you to prepare some multiple regression equations to estimate the effect of variables on fuel economy. The data for this study are shown below, and the dependent variable is miles per gallon. Complete parts a and b. Miles 43.5 36.2 32.9 39.9 36.7 19.6 19.8 20.4 19.9 20.2 Horsepower 49 69 50 72 61 109 142 139 101 98 Weight 1980 1890 1990 2090 1890 3365 3760 3580 3160 2730 a. Prepare a regression equation that uses vehicle horsepower and vehicle weight as independent variables. Let x1 be defined as horsepower and x2 be defined as weight. ? = ( ) + ( )x1 + ( )x2 (Round to four decimal places as needed.)
