(a) make a scatterplot. Choose the correct graph below.

(b) Describe any pattern in the plot. Be sure to identify any outliers, Choose the correct answer below.

A. There is a strong, negative linear association with some variation. There are no outliers.

B. There is a strong, positive linear association, There are no outliers.

C. There is a weak, positive linear association, Cars 1 and 2 appear to be outliers.

D. There is a weak, negative linear association. Cars 1, 2, and 5 are outliers

c) Find the correlation between these two variables.

r= ? (Round to three decimal places as needed.)

d) Use the correlation line to estimate the mileage of a car that weighs 4000 pounds. Does this seem like a sensible procedure? The estimated mileage of a car that weighs 4000 pounds is [?] MPG (Round to the nearest integer as needed )

D 0 0 0 N Car Highway MPG Weight (pounds) 1 29 3625 2 30 3975 3 30 3900 4 21 4275 5 19 4275 6 19 3975 7 27 4275 8 22 4275 9 26 3900 10 31 3625 11 17 4525 12 19 4525 13 16 4525 14 17 4525 15 18 4725 The accompanying data report characteristics of 15 types of cars sold in a certain country last year. One column gives the official highway mileage, and another gives the weight in pounds. Complete parts (a) through (d) below. :: Click the icon to view the data table of the characteristics for the cars. CR (a) Make a scatterplot of weight and highway mileage. Which variable do you think makes the most sense to put on the x-axis, and which belongs on the y-axis? Choose the correct answer below. O A. Highway MPG makes more sense on the x-axis because it is the response variable. Weight belongs on the y-axis. B. Weight makes more sense on the x-axis, given that one would want to understand variation on highway MPG. Highway MPG belongs on the y-axis. O C. Highway MPG makes more sense on the x-axis, given that one would want to understand variation on highway MPG. Weight belongs on the y-axis. OD. Weight makes more sense on the x-axis because the values associated with weight are larger than those for highway MPG. Highway MPG belongs on the y-axis. Make a scatterplot. Choose the correct graph below. OA OB. O c. OD 5000 3500-4 15 35 Highway MPG 1578 3500 5000 Weight (pounds) 3500 5000 Weight (pounds) 0 Highway MPG
