I said that the actual final will have the same kind of problems with the same
distribution of points. The column labeled "Sample Mean" indicates the average
scores students got on the sample final (handout
#32). The column labeled "Section Mean" indicates the average scores
students got on the sample final distributed in section.I reminded everyone that the exam is closed-book and closed-note. There is a two-page cheat sheet that will be attached to the test.
