Question
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 = 42 + 0.58*(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 42 on the final
B)If the final exam score is a 0, the expected midterm score would be -72
C) For every additional 1-point increase in a student's final exam score, the corresponding midterm score increases by 0.58 points
D)A student who scored a 0 on the final is expected to score a 42 on the midterm
E)For every additional 1-point increase in a student's midterm score, the corresponding final exam score increases by 0.58 points
F)If the final exam score is a 0, the expected midterm score would be 72
