Answers / Suggested Problems

Here are the missing answers from the review packet probability problems:
#11. 35/12 or 2 11/2
#19. 3/7
#20. 5/11 - This was a typo before! it is 5/11 NOT 5/14

And here are some suggested problems on Bayes' Theorem and binomial probability. The tree technique used for Bayes' Theorem in 7.4 is really helpful - I'd suggest trying to do those problems using the tree method if you can. Don't hesitate to email / meet with me with any questions!

7.4 - #7, 10, 11, 15-17, 28-31, 41-43, 60-62
7.5 - #7-9, 22-28, 38-40, 46-48, 52

HW 11 (last one!) - due 5/3

7.2 - #4, 8, 11, 16, 26, 27, 54-56, 60
7.3 - #13-15, 21, 30, 33-35, 58-60

HW 10 - due 4/27

6.2 - # 48, 50
6.3 - # 3, 6, 9, 12, 16, 20, 25, 27, 34
7.1 - #6, 11, 28, 31, 38, 46, 56

Remember there will be a quiz (last one of the semester!) this Thurs. covering material from HW9 and HW10.

HW 9 - due 4/20

5.7 - #4, 13, 18, 22, 30, 41, 42
6.1 - #2, 8, 9, 12, 18, 27, 32, 40, 45
6.2 - #2, 6, 10, 18, 23, 25, 26, 34

After looking at the calendar, I've decided not to have a quiz this week. We'll have one next Thursday (4/26) and that way the quiz can cover a little more material, and you'll have more time for questions on this assignment.

HW 8 - due 4/5

8.6 - #4, 7, 24, 31, 36, 50
8.7 - #1-8, 18, 28, 31-36, 56, 62, 63, 67, 72
5.2 - #11, 12, 14, 18, 19, 21, 24
5.3 - #13, 20, 24, 30, 35, 38
5.4 - #8, 10, 14, 20, 24, 31, 32, 40

(problems in purple added on 3/29)

There will be a quiz this week (3/29) over the last assignment, Homework 7.

HW 7 - due 3/23

This homework assignment is due the Friday after break, in my mailbox at 4 pm. It's a little longer than usual since we are not having an assignment due this week, but I think it is still do-able. We will not be having a quiz this week OR the week right after break, so there should be lots of time to ask questions on all of these.

8.1 - 15, 18, 23, 26, 28, 33, 34, 47, 48, 51, 52, 60
8.3 - 11, 12, 20, 21, 26, 28, 36, 39, 42, 43
8.4 - 5, 6, 10, 14, 15, 19, 20, 22, 23, 27, 54, 56
8.5 - 7, 8, 10, 25, 26

Have a great spring break!

This assignment is due Thursday, January 25th in discussion.
I know there has been some confusion over this first assignment, so if you need to turn it in late I will accept it in my mailbox (15 MacLean Hall) until 3:30 on Friday - I am leaving over the weekend so this way I will be able to bring it with me to grade.
