1. Dawn is doing a 30-day writing challenge to motivate her to work on the book she wants to publish. She keeps track of how many words per day she writes, and knows that her mean is 635 words with a standard deviation of 117. Yesterday, she wrote 721 words. On what percentage of days does she write less than she did yesterday?

2. The next day, Dawn determines that she wrote less than she did on 65.91% of days. Using the same information as above, how many words did Dawn write?
