# AP Statistics Assignment for Week of 4/21

This week, we’re going to try and finish the last bit of curriculum needed to start reviewing in earnest for the AP exam. The last topic is the remaining significance tests: The One-Sample T-Test, Two-Sample T-Test, and Matched Pairs T-Test.

## Complete by Thursday at 10:00 am

• Required: Watch Videos 7.1, 7.2, and 7.3 in Unit 7: Significance Tests on Stats Medic.
• Optional: Watch videos 7.4, 7.5, and 7.6. The first two videos cover forms of statistical inference that have been omitted from the AP exam, and so we will be skipping those. Video 7.6 is some more about Type I/II errors and Power. You’re welcome to watch it.
• Please click the red “Complete Step” button
• Required: Read the notes that I have left with each video (click theicon) for additional information, answers to anticipated questions, and tips about using the calculator
• Optional: Ask a question, answer somebody else’s question, or answer one of my “discussion question” prompts
• Optional: Finish reading Chapter 22 (pages 586-597 about the One Sample t-Test) and Chapter 23 (pages 614-624 about the Two Sample t-Test), as well as Chapter 24 (pages 634-648, about the Matched Pairs t-Test and Interval). Work on some of the odd numbered exercises in each chapter and check your answers in the back of the book.
• I highly recommend reading through Chapter 24, since the Stats Medic videos are a little light on this topic
• Optional: Watch the Hypothesis Tests for Means video from CollegeBoard’s live AP Statistics streams.
• Optional (strongly recommended): Complete 2015 Free Response Question #4 (as posted in Stats Medic) and score it using the video
• This question is from the actual AP exam in 2017, and is similar to what you could expect to see on our exam this year. I very strongly recommend you write an answer as thoroughly as you would if it appeared on the actual exam, then score yourself using the rubric video. You can expect that your AP exam questions will be scored in a similar way.
• If you do work on it, spend no more than 15 minutes completing it. Time yourself!
• Required: Complete the Unit 7 Practice Multiple Choice in Stats Medic
• You may skip questions 6, 7, 10, 16, and 17. You’re welcome to try them, but they deal primarily with the Chi-Squared and Regression inference procedures that we are omitting this year.
