HW 12


You will be tested on one of these questions in your TA session on Friday, May 10

Section 5.3 Problem 41
Section 5.4 Problem 53, 57 (for this problem you need to know that if X has gamma distribution with parameters α and beta then E(X) = α β and V(X) = α β2.
Section 5.5 Problem 64. (here a week means a "working week" so the five days Monday through Friday)
Two Hints:
1. it is better to divide the ten given random variables X1,. . . ,X10 into two groups of five random variables each, corresponding to morning and evening waiting times so

X1 = waiting time for Monday morning, Y1 = waiting time for Monday evening
...
X5 = waiting time for Friday morning, Y5 = waiting time for Friday evening

2. If a random variable X has uniform distribution on the interval [0,L] then E(X) = L/2 and V(X) = L2/12.

SLIDES FOR MY COURSE LECTURES

Here are typed slides for my lectures - the slides I used in class.

MIDTERM AND FINAL DATES

The first midterm will be in the lecture hall ARM 0126 on Thursday, March 7 and the second midterm will be in ARM0126 on Thursday , April 11.

The final exam will be in ARM0126 on Tuesday, May 21 from 1:30 - 3:30 PM

The homework quizzes, exams and final will be conducted according to the following rules.
1. No notes and NO "CHEAT SHEET".
2. No text.
3. No laptops
4. No calculators
5. No cellphones.

I will provide you on the exam with the formulas/tables you will need.

COURSE DESCRIPTION

We will cover the following topics in the order given..
1. All of Chapter 2.
2. All of Chapter 3
3. All of Chapter 4 except for the last two sections.
4. All of Chapter 5 but very little multiple integrals.
5. Random Samples (from handout) .
6. Some of Chapter 6 on point estimation.
7. Random intervals (from handout).
8. Some of Chapter 7 on interval estimations.
9. Moment generating functions (from handout).

COURSE GRADE

Your course grade will be determined from the following:

Test #1 50 points
Test #2 50 points
Homework 50 points
Final exam 100 points

Total 250 points

If you get 125 points or more you will get at worst a C-. If you get less than 125 points you
will get an F.

Your homework grade.
The week's homework will be assigned on my web page after the Thursday class

THE HOMEWORK QUIZZES

For the first 35 minutes of your TA section on Monday your TA will do the HW problems (if you are lucky he/she will do the one you are about to be tested on). At the end (fifteen minutes left) of your TA section your TA will pick one of the HW problems, you will put away your notes, do the problem and hand it in. In other words every week you will have a HW quiz. On occasion you may be asked to hand in an entire assignment or a part of one.
If you have an excused absence from a HW quiz (TA session) you have two choices:
1. Do the entire assigment and hand it in before the TA section in question (your TA will then grade the relevant question).
2. Otherwise you will receive the grade of E (excused) for the week's HW quiz and your homework total will be rescaled by the appropriate factor (larger than one).

All HW quizzes will count (I will not discount your two worst quizzes as is sometimes done).

MAKEUPS

There will be no makeup for the final exam or midterms except in case of medical emergency, family medical emergency, job interview or university related absence. If you have a medical emergency we will need a note verifying that from a medical professional. If you have a job interview we will need to see written evidence of that interview and interview date. In particular there will be no makeups for family vacations so be careful about buying airplane tickets.

If you do miss a midterm or the final without being excused notify me that you have missed the midterm or the final within a week. Otherwise you will receive a zero.

GRADING APPEALS

After each midterm or HW quiz students have one week from when the midterm or quiz is returned to appeal the grading. No appeals for regrading work done during the semester (including the midterms) can be made after the day of the final exam. Appeals for the final exam must be done in writing.
