The 2008 EPA fuel economy ratings for both highway and city driving are given for 25 randomly selected standard pickup trucks with 4 wheel drive. A scatterplot is shown below. 1. Describe what you see in the scatterplot. 20 19- 18- g 17- 16- Highway mpg 15- 14- 13- 12- 11- 2008 Fuel Economy Ratings for standard 4WD Pickup Trucks 10 12 14 City mpg 16 18 2. Is one of the points on the scatterplot unusual to you in comparison to the other points? Explain why you think this point is unusual. 3. In this situation, is it more reasonable to simply explore the relationship between the two variables or to view one of the variables as an explanatory variable and the other as a response variable? In the latter case, identify which is the explanatory and which is the response variable. 4. Based on this scatterplot, what does this tell you about the relationship between highway mpg and city mpg for trucks in this category?
