5. Chest Sizes and Weights of Bears When eight bears were anesthetized, researchers measured the distances (in inches) around the bears’ chests and weighed the bears (in pounds). Minitab was used to find that the value of the linear correlation coefficient is r
0.993.

a. Is there a linear correlation between chest size and weight? Explain.

b. What proportion of the variation in weight can be explained by the linear relationship between weight and chest size?
