to a complete stop when hitting the brakes. The correlation coefficient between the values is 0.81.
-Would it be appropriate to say that a car's speed causes its stopping distance?

• A)Yes, the scatterplot shows a strong linear association, so the faster a car is going, the longer it takes to stop it.
• B)Yes, since the correlation coefficient is close to 1, we can conclude causation.
• C)No, since the correlation coefficient does not equal 1, we cannot conclude causation.
