Wednesday HW! (and an extra credit opportunity!)

Tonight please complete the "elevator question" on the back of the 2010 Free Response we worked on in class! You must complete this problem in two ways--using the "sampling distribution method" and using the "combining random variables method" to receive full credit!

Today's Notes: If you were out today (or just want to look at this example), here's the 2010 free response we worked on in class--the work below shows how to answer part b using two different methods!

HW Extra Credit Opportunity:
A student from Wethersfield high is doing a Stat project and needs students to fill out this survey to generate some data! Do it! Please! Help out a fellow statistician!

• Do this survey to help out a fellow AP Stat student!
• Take a picture of the screen stating that you've completed the survey, then show it to me in class (by Friday) and you'll get some hw extra credit!

Tomorrow in class we'll discuss some details about the structure and scoring of the exam, and we'll start to get into the investigative task--see you there!
