Part 3 c. How strong is the relationship between X and Y? Explain.

A. X and Y have no correlation.

B. X and Y have a perfect negative correlation because all points fall on a straight line with a negative slope.

C. X and Y have a perfect positive correlation because all points fall on a straight line with a positive slope.
