Refer to Exercise 11.18. After the least square line has been obtained, the following table can be used (1) to compare the observed and predicted values of y and (2) to compute SSE.

a. Complete the table.

b. Plot the least squares line on a scatterplot of the data.
Plot the following line on the same graph:
yn = 8.20 - .45x

c. Show that SSE is larger for the line in part b than it is for the least squares line.
