Suppose this relationship is very regular, as shown by the following data on speed (miles per hour) and mileage (miles per gallon): l.Il MPG Speed 20 30 40 50 60 70 80 Mileage 21 26 29 30 29 26 21 Make a scatterplot of mileage versus speed. Show that the correlation between speed and mileage is r = 0. Explain why the correlation is 0 even though there is a strong relationship between speed and mileage
