Assume that you have paired values consisting of heights (in inches) and weights (in lb) from 40 randomly selected men. The linear correlation coefficient r is

0.433.

Find the value of the coefficient of determination. What practical information does the coefficient of determination provide?

A.The coefficient of determination is 0.813. 18.7% of the variation is explained by the linear correlation, and 81.3% is explained by other factors.

B.

The coefficient of determination is

0.187.

18.7%

of the variation is explained by the linear correlation, and
