5. Is there any relationship between the engine displacement and consumption (miles per gallon)?
6. Is there any relationship between the vehicle weight and consumption (miles per gallon)?
7. Is there any relationship between the horsepower, consumption (miles per gallon), engine displacement, and vehicle weight?
8. Determine a linear relationship between the consumption (y) and horsepower (x₁), engine displacement (x₂), and vehicle weight (x₃)
