a. Use the linear regression equation from Part C to calculate the predicted adult
weight for each birth weight. Round to the nearest hundredth. Enter these in the third
column of the table. (2.5 points)
b. Find the residual for each birth weight. Round to the nearest hundredth. Enter these
in the fourth column of the table. (2.5 points)
c. Plot the residuals. (3 points)
