MoNdAy Hw (and extra credit HW opportunity)

**Please consider your schedule for our April break session--I will pass out an initial sign up sheet tomorrow to get a head count*

• April Break Session: Wednesday 4/11 from 10:00 - 1:30
• You will be given a (heavily weighted) take home test over April break--this will be a practice exam, covering all content we have learned, to start our preparation for May 17th
• During the review session you will have the opportunity to work in groups, to ask questions (of me) and your classmates, and to study (by competing the take home test) in a structured environment....
• Best case scenario = you finish and turn it in that day!

Here's Monday's homework:

• Please complete the t-interval and t-test for the two remaining slides for chapter 23 (in your notes); or, these are on the last two pages if you took the packet
• If you use the slides you should paste these contexts into your notebook and complete these problems there!
• The context is about the "mean number of credit cards undergraduates report carrying"
• See below if you need the slides/contexts

Extra Credit HW Opportunity: Due by Wednesday (more t-practice)

• To earn this extra credit you must complete the problems below AND use a different color pen/pencil to grade your work (using the back of the book)
• It's ok if you don't have all the right answers initially, just show some corrections if you had something wrong! And show some checks or correct marks for everything that's right!
• Pages 541 - 545: 1bac, 13, 17ab, 23abc
• *We will learn how to do #1abc tomorrow in class, or you can read about this on pages 522-525 (start at "Gosset's t" and read through the yellow boxes on p. 525
• If you were absent today you should also read these pages--today in class we spent some time discussing the t-distribution

Monday HW Contexts:

• For #2 in bold below please use your confidence interval to "test this claim."
• Then, on the following slide, you will use a hypothesis test (T Test) to test this claim

Heres our t-test example from class (Thursday notes):
