2. A study was conducted to investigate the effect of vehicle weight on gas mileage. The following random sample was collected where x is the weight of a vehicle in pounds and y is the miles per gallon. x (pounds) у (mpg) 3900 2600 | 22.0 3500 | 16.1 |2900 |18.8 2000 23.4 15.7 Refer to your EXCEL Homework for the calculations. Write a sentence interpreting the value of the slope of the regression line. Give a brief explanation of the meaning of the coefficient of determination in the context of this problem. If a vehicle weighs 2300 pounds, what does the least-squares line predict for the miles per gallon? Is this interpolation or extrapolation? What does the correlation coefficient tell us about the relationship between weight and gas mileage? (Include a statement about direction, form, and strength.) a. b. с. d.
