The file S02_10.xlsx contains midterm and final exam scores for 96 students in a corporate finance course.
a. Do the students’ scores for the two exams tend to go together, so that those who do poorly on the midterm tend to do poorly on the final, and those who do well on the midterm tend to do well on the final? Create a scatter plot, along with a correlation, to answer this question.
b. Superimpose a (linear) trend line on the scatter plot, along with the equation of the line. Based on this equation, what would you expect a student with a 75 on the midterm to score on the final exam?
