Answers to exercises in the book

Exercises

  1. Agresti exercise 7.11, 7.17 and 7.20. These three exercises from Agresti can all be answered with pen and paper (using RStudio as a calculator).

  2. In the exercises of lecture 1-1 and lecture 2-1 there were exercises concerning the data "Rock fries your brains". If you did not look at the first one yet go back and open the corresponding Rmd file and run it to read a bit about the data. Today we will compare the control group with the Mozart group in the file rock-fries-your-brains-3.Rmd; so download it and answer the questions in it.

  3. Finish old exercises.
