Question 28 (1 point) For several year 2005 car models. horsepower and gas mileage (MPG, or miles per gallon) were measured. The scatterplot is given below. MPG 100 150 200 250 300 Based on this graph, correlation between Horsepower and MPG O is a meaningless number because correlation does not imply causation. 0 would change if we measured gas mileage in \"kilometers per liter" instead of "miles per gallon." 0 would not change if we measured gas mileage in "kilometers per liter" instead of "miles per gallon." O is positive because (as the plot shows) more powerful cars typically have lower gas mileage
