Refer to Exercise 11.14. After the least squares line has been obtained, the table below (which is similar to Table 11.2) can be used for (1) comparing the observed and the predicted values of y and (2) computing 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: 
 = 14 – 2.5
.
c. Show that SSE is larger for the line in part b than it is for the least squares line.
Exercise 11.14
The following table is similar to Table 11.2. It is used for making the preliminary computations for finding the least squares line for the given pairs of x- and y-values.
