In a certain statistics class, the past data has indicated that there is a positive, linear relationship between a student's midterm exam score and their subsequent final exam score. The LSR model for this relationship is given by:


final score = 60 + 0.4*(midterm score)


From the choices below, the best interpretation of the intercept is:


a. A student who scored a 0 on the midterm is expected to score a 60 on the final.

b. If the final exam score is a 0, the expected midterm score would be -150.

c. A student who scored a 0 on the final is expected to score a 60 on the midterm.

d. For every additional 1-point increase in a student's midterm score, the corresponding final exam score increases by 0.4 points.

e. If the final exam score is a 0, the expected midterm score would be 150.

f. For every additional 1-point increase in a student's final exam score, the corresponding midterm score increases by 0.4 points.
