Weekend HW!

Weekend Responsibility #1: Please complete the "test and interval" worksheet (with 4 questions) provided in class or below.

• This assignment is a great way to review/self assess a full confidence interval free response, a full hypothesis test, and to see how these are similar/different!
• I would recommend drawing a line down the middle of your paper and doing the test/interval side by side...
• Do question 1 on one side...
• Do quesitons 2, 3 on the other side
• Answer question 4 at the bottom!
• I will provide an answer key on Monday!

Weekend Responsibility #2: EARN STAMPS!

• Remember, stamps are part of your classwork grade!
• Any stamps you have that are over the total you'll need at the end of the quarter become points that are added to past classwork grades!
• For example, if you got a 14/20 on the sub work, but you have 6 more stamps then you need, that 14/20 becomes a 20/20!
• In other words, earn lots of stamps!
• Today I passed back the sub work (multiple choice) you did on Tuesday--you can complete questions 4, 5, 11, and 12 in this packet for stamps!
• One stamp per correct answer....
• If you were out, or if you're in period D and your teacher is a moron and forgot to pass these back, here are the questions:

Today's Class Recap:

• Stamp = Write a conclusion given a context/p-value
• Classwork = "Free Soda" example from our slides
• Worked in our group to complete this full hypothesis test
• Gave a 14 minute time limit (this is roughly how long we'd have on the AP exam for this type of question)
• Whole Class Discussion:
• What is a two tailed test? A one tailed test? 
• (This "free soda" example was a two tailed test
• How can we label the Normal model we sketch for a two tailed test? 

On Monday we'll wrap up chapter 20 by finishing our discussion about two tailed tests; then we'll look at some more questions to strengthen our understanding of p-values, and we'll end with an AP Free Response (that we'll most likely finish for homework).

Then, Tues-Friday we'll learn chapter 21 (more stuff about hypothesis tests--types of error, alpha, beta, power), leading up to a test on everything confidence intervals and hypothesis tests on Monday, March 18.
