Essay
Analyze the regression results below (n = 33 cars in 1993) using the concepts you have learned about multiple regression. Circle things of interest and write comments in the margin. Make a prediction for CityMPG for a car with EngSize = 2.5, ManTran = 1, Length = 184, Wheelbase = 104, Weight = 3000, and Domestic = 0 (show your work). The variables are CityMPG = city MPG (miles per gallon by EPA rating); EngSize = engine size (liters); ManTran = 1 if manual transmission available, 0 otherwise; Length = vehicle length (inches); Wheelbase = vehicle wheelbase (inches); Weight = vehicle weight (pounds); Domestic = 1 if U.S. manufacturer, 0 otherwise.
