  1. So now I'm going to give you a touigh question. Which ironically is the same
  2. exact question I asked you before. But this time use the Z table to approximate
  3. the proportion of people who have less than 240 Facebook friends. So this might
  4. be tricky, but spend some time on it, and I think you can do it. And remember,
  5. whenever you are doing math, think about it logically. 240 is about here. So
  6. should your z score be negative or positive? Should it be between zero and one,
  7. or between one and two?
