**MathMate**, Sunday, June 23, 2013 at 6:01amThe answer should be a negative number as the numbers increase as x becomes smaller.

The correlation coefficient lies between -0.2 and -0.3.

Please post your equation for r again to see if it is interpreted correctly.

Most of the time mistakes come from incorrect interpretation of expressions.
