Marketing Graduate: GPA, X: Starting Salary, Y (Thousands of Dollars):
1 3.26 33.8
2 2.6 29.8
3 3.35 33.5
4 2.86 30.4
5 3.82 36.4
6 2.21 27.6
7 3.47 35.3

The chairman of the marketing department at a large state university undertakes a study to relate starting salary (y) after graduation for marketing majors grade point average (GPA) in major courses. To do this, records of seven marketing graduates are randomly selected, and the data shown below on the left are shown:

When a least squares line is fit to the 7 observations in the starting salary data, we obtain SSE = 1.438.
