Question 14

A high school wants to predict her students' score on a midterm exam y, given the number of hours a student spent studying x1 and the student's average homework grade x2. She obtains the multiple regression equation yˆ=−2.662+4.686x1+0.753x2. Predict the midterm exam score of a student with an average homework grade of 85, who spent 4 hours studying, rounding to the nearest integer.

Do students reduce study time in classes where they achieve a higher midterm score? In a Journal of Economic Education article (Winter, 2005), Gregory Krohn and Catherine O’Connor studied student effort and performance in class over a semester. In an intermediate macroeconomics course, they found that “students respond to higher midterm scores by reducing the number of hours they subsequently allocate to studying for the course”. Suppose that a random sample of n=8 students who performed well on the midterm...
