C2L2 unclear wording

Banged my head on this for a while. It starts off with “Calculate an average rating for each movie in our collection where…” which I interpreted as I need to calculate the Average and then use it in the scaling, but couldn’t figure out a clear way to do that.

After poking around for a while I figured out I was making this question harder than necessary. You don’t need to find the average for the set, you just need to figure out how to calculate the normalized vote, which they give you most of in the handout.
