I got the My and xbar. However, I keep messing up when doing the ybar and the Mx; I messed up like 5 times (no laughing). This time I got:

ybar: 24

Mx= 256

are these right?

I would show my work but that's A LOT of typing and the work on my paper is really really messing because I kept messing up. I know it's basically just plugging in numbers to the formula, but I mess up at every and any little thing.
