Help fast Fuel efficiency, measured in miles per gallon, is a
measure often considered by shoppers looking for a
new car. The scatterplot shows the vehicle weight of
15 car models in pounds, plotted against their highway
fuel efficiency.
How would the value of the correlation coefficient
change if the car weights were recorded in kilograms,
rather than pounds?
