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 = 58 + 0.42*(midterm score)

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

a. A student who scored a 0 on the final is expected to score a 58 on the midterm

b. If the final exam score is a 0, the expected midterm score would be 138    

c. For every additional 1-point increase in a student\'s final exam score, the corresponding midterm score increases by 0.42 points

d. If the final exam score is a 0, the expected midterm score would be -138

e. A student who scored a 0 on the midterm is expected to score a 58 on the final

f. For every additional 1-point increase in a student\'s midterm score, the corresponding final exam score increases by 0.42 points

Solution

e. A student who scored a 0 on the midterm is expected to score a 58 on the final

This is right as intercept means y value when x =0

Or final score when midterm score = 0
