Past data has shown that the regression line relating the final exam score and the midterm exam score for students who take statistics from a certain professor is

final exam = 50 + 0.5 × midterm

One interpretation of the slope is:

A)

a student who scored 0 on the midterm would be predicted to score 50 on the final exam. 

B)

a student who scored 0 on the final exam would be predicted to score 50 on the midterm exam. 

C)

a student who scored 2 points higher than another student on the midterm would be predicted to score 1 point higher than the other student on the final exam. 

D)

none of the above are an interpretation of the slope.
