The accompanying datarepresent the weights of various domestic cars and their gas mileages in the city for a certain model year.Suppose that we add Car 12 to the original data. Car 12 weighs 3 comma 3053,305 pounds and gets1919 miles per gallona) Compute the linear correlation coefficient with Car 12 included.The linear correlation coefficient with Car 12 included is r-?(Round to three decimal places as needed.)b) Recompute the linear correlation coefficient with Car 13 included. How did this new value affect yourresult?The linear correlation coefficient with Car 13 included is r-?t) Why does this observation not follow the pattern of the data?Question
