Question
In a certain statistics class, past data has indicated that there is a positive, near relationship between a student's midterm exam score and his/her subsequent final exam score. The regression line for this relationship is given by: final score = 52 + 0.48* (midterm score) From the choices below, the best interpretation of the intercept is: If the final exam score is a 0, the expected midterm score would be 108. If the final exam score is a 0, the expected midterm score would be -108. A student who scored a 0 on the midterm is expected to score a 52 on the final. A student who scored a 0 on the final is expected to score a 52 on the midterm. For every additional 1-point increase in a student's midterm score, the corresponding final exam score increases by 0.48 points on average. For every additional 1-point increase in a student's final exam score, the corresponding midterm score increases by 0.48 points on average. From the choices below, the best interpretation of the slope is: If the final exam score is a 0, the expected midterm score would be 108. If the final exam score is a 0, the expected midterm score would be -108. A student who scored a 0 on the midterm is expected to score a 52 on the final. A student who scored a 0 on the final is expected to score a 52 on the midterm. For every additional 1-point increase in a student's midterm score, the corresponding final exam score increases by 0.48 points on average. For every additional 1-point increase in a student's final exam score, the corresponding midterm score increases by 0.48 points on average.Explanation / Answer
