If we use statistical methods to conclude that there is a correlation (or relationship or association) between the weights of cars and the amounts of fuel consumption, can we conclude that adding weight to a car causes it to consume more fuel?

The x-values are weights (in pounds) of cars; the y-values are the corresponding highway fuel consumption amounts (in mi/gal).

Car Weights and Highway Fuel Consumption Amounts Weight (lb) Highway Fuel Consumption

Car Weights and Highway Fuel Consumption Amounts Weight (lb) Highway Fuel Consumption (mi/gal) 4035 26 3315 3565 29 4115 3650 31 29 30
