Hector surveyed 500 people and asked them how far they drive to work and what the last digit of their phone number is. He used the results to make a scatter plot. What type of association should he expect to see in the scatter plot?

Which scatter plot has a stronger association?

• Scatter Plot A because the points are closer together.

• Scatter Plot B because the points are further apart.
