You own a company that makes drum sticks and you wonder how long they last. You ask 472 drummers how long their most recent pair of sticks lasted in weeks. After analyzing the data you forget what the actual mean was but you do remember the standard deviation was 3.5 (because that was your birthday, March 5th) and the last pair of sticks you used lasted 44 weeks and their Z score was 1.8. How long do sticks last on average (what is the mean)?
