3 Day Weekend HW (and Monday's hw, and an extra credit hw...)

**Please consider your schedule for our April break session--I will pass out an initial sign up sheet on Monday 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!

1.) Weekend HW = "Inferences for Means: T Tests and T Intervals (More Practice!)" packet.

• If you were absent today and need a copy of this assignment please send me an email and I will respond with an attachment, or use the images below (carofano.fm@easthartford.org)
• YOU ARE EXPECTED TO BE RESPONSIBLE AND COMPLETE THIS EVEN IF YOU WERE OUT!
• You will receive a 0 if you do not complete this for Monday!
• See below for images of the weekend homework
• #2: Finding sample size....
• In #2 (MC) you are asked to find sample size....
• We'll use the same logic as before--we're given the margin of error, so we'll use the margin of error equation to solve for n. This gives us...
• ME = t*(Sx/sqrt(n))
• However, we cannot find t* without df, or without n--so instead we just uze z* in this case
• So we set up the equation ME = z*(Sx/sqrt(n)) , substitute the correct values, and solve for n

2.) Have time and feeling ambitious? Here's Monday's homework:

• Monday Homework: complete the t-interval and t-test for the two remaining slides for chapter 23 (in your notes), or 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

3.) 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
