You want to estimate the linear relationship between class attendance and performance on the final. You believe the relationship takes the following form

grade=+ attendance+

You have the following data

Student	Attendance	Grade on final
Kyle	32	96
Stan	24	80
Eric	26	84
Kenny	15	72

5. For Eric (attend=26, grade=84), in other words, what is the residual e for him? Recall the residual is the difference between the actual exam grade and the predicted exam grade. (Friendly note: residual can be positive or negative.)

(Please round your result to the second digit after the decimal point.)
