• 14) Here are some of the solutions I promised in class: (4/26/2002)
  
  • Solution for the second Chi-Square Test for Independence example (page 218 in the lecture notes).
  • Quiz 12: Blanc (for practice) and Solution.
  • Fall 2001 Final: Blanc (for practice) and Solution.
  
  
• 15) Here are the scores for Quizes 1 through 12, Midterm 1 & 2, and the Total for Section 003 and Section 004. The first 12 columns contain the scores for the 12 Quizes, the next 2 columns the Quiz scores that will be dropped. Column 15 contains the Bonus points from Quiz 12 and Column 16 (TotalQ) the Total for the Quizes. The next 2 columns contain the scores for Midterm 1 & 2 (Mid1 Mid2), followed by the Total and the percentage (so far, 600 points could be obtained).
  
  There is no name, SSN, or any other identification on this page. You need to know (or guess) what your scores for Midterm 1 & 2 are to identify your Total score.
  
  If you cannot identify yourself or if some numbers are incorrect, please talk to me AFTER the final and bring the quizes and midterms with you that show different scores than the ones reported on the Web page.
  
  Based on the previous grading criteria for quizes and midterms, an A- starts at about 87%, a B- at about 73%, a C- at about 60%, and a D- at about 47%. These cutoff percentages are not fixed and may slightly change after the Final, but should give you some idea how many points you need approximately to obtain a particular grade.

• 16) Sorry, but I am still grading... It takes far more time than initially expected. I will be done with grading and have final grades posted by late Friday night at the best... Sorry for the delay. (5/2/2002)
  
  
• 17) Finally - here are the points for the final exam and the resulting grades. Again, you have to identify your midterm scores and then check your final scores in the file for your section. New columns contain scores for each question in the final, the total in the final, the grand total, the %, and the corresponding grade: Section 003 and Section 004.
  
  The final was worth 40% of the overall grade. So, the number of points for each question has been multiplied by a factor of 4. I will provide solutions to the final on this Web page early next week. If you want to look at your final, I will be in my office this Tuesday from 10am to noon (please e-mail for an appointment later in the summer).
  
  Final grade cutoffs were similar to the cutoffs posted earlier, with 5% increments for (almost) all grades. This means: below 45: F, above 45: D, above 52: D+, above 57: C-, above 62: C, above 67: C+, above 72: B-, above 77: B, above 82: B+, above 87: A-, and above 90: A.
  
  Please e-mail in case of any questions. (5/5/02).
