The graph at right compares the gas mileage to the weight of numerous vehicles.
Describe the association between these two quantities.
Consider these questions:
1. Is there a linear association?
2. Are there any outliers? (Points that do not fit in nicely with the rest of the data points).
3. Why is the data in two clusters? What might this imply?
3. Two different types of vehicles could have been used. Try answering the first two questions on your own.
