FINAL EXAM (50 of the total 400 points from
homework) The Final Exam is cumulative, but Units #22 to #31
(hypothesis testing and confidence intervals) will be much more heavily
emphasized; you should know both how to use the TI84 calculator and how to
read SPSS output. A special tutor schedule for Final Exam Week will be
posted before the end of the last week of classes. All Self‑Test Problems and all odd number
exercises can serve as a review for the final exam, with more heavy emphasis
on those from Units Exercise #22 to #31.
A special list of oddnumbered problems that can be used as a “sample
final exam” is displayed at the end of this webpage. Answers to SelfTest Problems can be found
near the end of each unit in the text, and answers to odd numbered exercises
can be found available here.
