A few years ago Ken Okamoto-Kaminski and I did the exercises in Agresti & Finlay “Statistical Methods for the Social Sciences“. We did the exercises for which there is a key, and the document shows how we solved all these exercises. These are my notes, and everything is handwritten. The edition we used had a misprint in the answer for exercise 3.5.f (I’ve checked this with Agresti, so the misprint should be fixed in newer editions).
