# Homework

The solutions to the practice problems are at the end of the book and do not need to be handed in. Graded assignments should be typed (preferably using R Markdown) or neatly hand written and scanned. Data for the homework assignments, and for within the chapters too, can be downloaded here. Or alternatively all the data is included in the `openintro`

R packge (use the `data(package = 'openintro')`

command to list all the datasets available in that package).
