Announcements

Please submit your labs in .doc or .pdf format.
Due to lack of demand, Math 11L TAs Will Garner and Rosanna Haut will no longer hold office hours outside of their section times.
Lab 5 has been graded. Your score may not be an integer. If the comments box shows your score is 13.5/15, then that is your score, even if WebCT appears to round it to 14.

Exams

Here is a link to the first midterm exam, and here is a link to the solutions. The mean was 85, the median was 89, and the standard deviation was 12.8. Approximate grade ranges are as follows: 93-100 = A, 80-92 = B, 60-79 = C, 50-59 = D, 0-49 = F.

Homework Assignments

You should turn in your homework assignments at the beginning of your section on Tuesdays. Alternatively, you can drop off your assignment in your TA's box, which is on the 6th floor of Applied Physics and Mathematics, before 9:30 AM on the due date. (If you do this, please write the time of your section at the top of your homework.) Please work carefully, and show the steps in your calculations, not just the final answer.

Odd-numbered problems will rarely be assigned because full solutions appear in a student's solutions manual. Answers to selected even-numbered problems will be posted below, so that you can get some immediate feedback. However, answers will not be posted for all problems. Even-numbered, end-of-chapter problems are typically similar to the preceding odd-numbered problem, so you are encouraged to work the preceding odd-numbered problem first and check your answer to make sure you are on the right track.

Homework solutions will appear below after the assignments are due. The solutions will be password protected, and they are for your personal use only. Please do not distribute them to anyone not enrolled in Math 11.

Reading: For this assignment, the relevant portions of the textbook are Chapter 4, pp. 79-88 of Chapter 5 (stop before the section on Timeplots), pp. 111-117 of Chapter 6, and Chapter 7 (but skip the sections on Kendall's Tau and Spearman's Rho). I also suggest that you skim the very short chapters 1 and 2, and pp. 19-23 and 33-34 of chapter 3.

Note: for hypothesis testing problems, you must show how you calculated your test statistic. You do not need to show work for the step of going from the test statistic to the p-value, as this step comes from tables or a calculator. You should always write a concluding sentence in which you explain your conclusion in the context of the problem.

Academic Integrity

Remember that you must abide by the following rules when completing your homework and computer lab assignments. The full academic integrity policy for the course is available here. A link to UCSD's policy on integrity of scholarship is available here.

You must write up your final solutions independently.
You may not copy solutions from another student or from any other source.
If you consult any sources other than your textbook or discuss the problems with anyone other than the instructor or TA, you must acknowledge this on your homework and indicate on which problems you received help.
Your lab write-ups must be based on calculations that you carried out in MINITAB yourself.
You may look at old exams posted on the course web page, but you may not look at other materials (such as homework or computer lab solutions) from previous Math 11 classes.
You may look up general course topics on the internet, but you may not look for solutions to specific homework problems on the internet.

Old exams

Everyone may look at old Math 11 exams and solutions, to which links appear below. Please note that this year's exams will be different. Working through these old exams may be helpful, but is not a substitute for reviewing your notes, homework, and labs, and keeping up with the class on a daily basis.

Problems that you should be able to do by the time of this year's first midterm are listed in parentheses. Additional problems that you should be able to do by the time of this year's second midterm are listed in brackets. You should be able to do all problems on these exams by the time of this year's final exam.
