Will resolve YES, if in my next statistics meetup my group unanimously agrees to the statement: "All Review Exercises from Chapters 15, 16, 17, 18 and 19 from "Statistics by Freedman, Pisani and Purves" have all been done by [me] and at least 50% of the have been solved correctly."

Of course I will also attempt to solve all the Standard Exercises, but since there are Solutions to those in the back of the book, it's no fun including them in the bet.

Right now I'm still finishing Chapter 15 and the other chapters usually took me ~4-8 hours of focused work and my track record of getting the exercises done in time is quite bad.
