An engineer wants to determine how the weight of a car, x, affects gas mileage, y (MPG). The following data represent the weights of various cars and their miles per gallon. Make a scatter plot. (Carefully choose units on both axes; no need to start at 0, but make them not too small! Do not omit axis labels and the title.) Describe the relationship between Car Weight and MPG. Justify. Give the correlation coefficient to three decimal places. (CV are listed on the last page) Car Weight (pounds), x Miles per Gallon, y A B C D E 2750 2940 3265 3765 4120 25.4 25.1 25.4 19.8 20.2 'f it makes sense, give the equation of the regression line (of MPG on pounds of weight; use at least 3 significant, nonzero, digits) and draw this line on the plot (be precise! use a ruler.)
