70 10 points 60 50 40 MPG 30 20 10 10 20 30 40 50 60 Weight (100 Lbs) Note that automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). Suppose we have a collection of cars, we measure their weights and fuel efficiencies, and generate the following graph of the data. (Source: http://lib.stat.cmu.edu/DASL/Datafiles/carmpgdat.html) Which of the following can possibly be the regression line for this data set. A. OY = -1.11X + 5.17 B. OY = 1.11X + 68.17 C. OY = -1.11X + 68.17 D. OY = 1.11X + 5.17
