Suppose a regression model predicts final exam score based on homework(est=.97, p=.55), clicker(set=-2.69, p=.59), Exam 1 (est=.40, p=.001), Exam 2 (est=.14, p=.12) with an intercept (b=36.32, p=.001). What is the predicted final exam score for someone scoring a 0 on homework, clickers, Exam 1, and Exam 2?
