Suppose the government would like to investigate the relationship between the engine size of sedans and the miles per gallon (MPG) they get. The accompanying table shows the engine size in cubic liters and rated miles per gallon for a selection of sedans. Complete parts a through e below. Click the icon to view the data table. a. Calculate the sample covariance. sxy= (Round to three decimal places as needed.) b. Calculate the sample correlation coefficient. rxy= (Round to three decimal places as needed.) Engine Size versus MPG
