# Question: Assume that in a political science class the teacher gives

Assume that in a political science class, the teacher gives a midterm exam and a final exam. Assume that the association between midterm and final scores is linear. The summary statistics have been simplified for clarity.

Midterm: Mean = 75, Standard deviation = 10

Final: Mean = 75, Standard deviation = 10

Also, r = 0.7 and n = 20.

According to the regression equation, for a student who gets a 95 on the midterm, what is the predicted final exam grade? What phenomenon from the chapter does this demonstrate? Explain. See page 199 for guidance.
