(Notes soon)

• Review the examples of Bayes’ Theorem we discussed in class, and also the definitions of independence.

• Answer the questions on page 1 of the handout “Conditional Probabilities and Contingency Tables”: here is a much improved version which corrects some bad references and improves the second page problem (and explains the notation) – please use this version!

• Also answer the following:

For problem 2.4.25, if we find that the ball bearings are defective, what is the probability that they came from Company 3?

• Do these problems from the textbook:

p. 52 #2.4.45

p. 58 # 2.5.1, 2.5.3, 2.5.7, 2.5.9

Also, if you have not yet joined our Datacamp group, please check your email for the invitation to join our Datacamp group. The email was sent to whatever email address is your main address in CUNYFirst.  It is important that you join the group as soon as possible, as there may be a deadline. Also, you must join using the email to which your invitation was sent. I believe that you can also go directly to Datacamp and create an account using that email, and then you should see a notification in Datacamp that you have been invited. The notifications are under the little icon shaped like a bell on the upper right side of the webpage.

There will not be a Quiz on Wednesday.

Don’t forget, if you get stuck on a problem, you can post a question on Piazza. Make sure to give your question a good subject line and tell us the problem itself – we need this information in order to answer your question. And please only put one problem per posted question!
