No, it is completely erratic. D. Yes, it is approximately normal. The table lists weights (pounds) and highway mileage amounts (mpg) for seven automobiles. Use the sample data to construct a scatterplot. Use the rst variable for the x-axis. Based on the scatterplot, what do you conclude about a linear correlation?
