Hi all!
Problem set 1, question 3 uses a dataset that I didn't include. It's in the link at the bottom of this announcement.
Also, some of the questions cover material that we haven't gone through yet. You can just skip those questions, but make sure to note that you're skipping it because we haven't covered it yet.
Note: These questions will be added to the next Problem Set, so if you want to get a jump on it, you can go ahead and answer them and just put them into your answers for Problem Set #2.
