Suppose you are interested in the effect of skipping lectures (in days missed) on college grades. You also have ACT scores and high school GPA (HSGPA). You run the following regression model numbers in parentheses below each coefficient represent standard errors of each coefficient) colGPA =2.52+0.38H SGPA+0.015 ACT-0.5skip (0.2) (0.3) (0.0001)
(a) Interpret the intercept in this model.
(b) Interpret BACT from this model.
(c) What is the predicted college GPA for someone who scored a 25 on the ACT, had a 3.2 high school GPA and missed 4 lectures. Show your work.
(d) Is the estimate of skipping class statistically significant? How do you know? Is the estimate of skipping class economically significant? How do you know? (Hint: Suppose there are 45 lectures in a typical semester long class).
