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?

1. Consider the following data on the heights and weights of several high school senior boys. (a) Make a well-labeled scatterplot. Height Weight (inches) (pounds) 71 185 75 230 68 145 170 150 70 69 (b) Describe the relationship between the height and weight of a senior boy at this school. 2. In each of the following 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. (a) The height and weight of senior boys in problem 1. (b) Amount of fertilizer used per acre and the crop yield per acre. (c) Minimum daily temperature and heating costs (d) The score on a test and the amount of time spent watching TV the previous night. (e) The height of a husband and the height of a wife.
