An engineer wanted to determine how the weight of a car affects gas mileages. The following data represent the weight of various cars and their gas mileage.

Car weight pound miles per gallon

A 3590 18

B 2690 26

C 3180 23

D 3565 20

E 3680 19

(a) Compute the linear correlation coefficient between the weight of a car and its miles per gallon. r = (.......) (Round to three decimal places as needed)

(b) Comment on the type of relation that appears to exist between the weight of a car and its miles per gallon based on the scatter diagram and the linear correlation coefficient.
