AP Statistics Assignment for 10/4

Read pages 154-161 (up to the section on “Straightening”). From the exercises on pages 168-173, do 9, 10, 14, 15, 41, 42.

There will be a reading quiz about this section in class tomorrow, and we will have a more thorough, though short, quiz on chapter 6 on Friday, October 6.

Also, check out Guess the Correlation, a surprisingly addictive online game where you, surprise, surprise, guess the correlation value for a randomly created association. How high can you get your score?
