Problem 1: Oil Production Data: The Data in the following are the annual world crude oil           production in millions of barrels for the period 1880-1988. The data are taken from Moore and McCabe( 1993, p. 147). Construct a scatter plot of the oil production variable (OIL) versus Year and observe that the scatter of points on the graph is not linear. In order to fit a linear model to these data, OIL must be transformed. Construct a scatter plot of...
