The table lists weights (pounds) and highway mileage amounts (mpg) for seven automobiles. Use the sample data to construct a scatterplot. Use the first variable for the x-axis. Based on the scatterplot, what do you conclude about a linear correlation? Weight (lb) 3185 3370 3895 4180 4435 2425 Highway (mpg) 30 Which scatterplot below shows the data? O A. O B. O C.
