Thread: First movement about the mean

Last question of the day, I promise. LOL

I need to find the first movement about the mean of X. I found mu, which is the mean. Do I then substitute that into (X-mu)*p(x), or is mu the final answer? My notes say that mu is the first movement about the origin, and the variation is the second movement about the mu.
