For the computer homework questions, please use the report format:

First, answer the questions in complete sentences, using the output text

or figures as evidence to support your answer; then, attach the program

codes (with comments to code more readable) as an appendix by the

end of the statistical report. When you copy and paste the text part,

please box them and treat them as tables. Please label all your figures

and tables. The code in your appendix may contain extra code you have

used or explored, but should be executable (no errors).
