Statistics, HALP D: - September 17th 2010, 04:25 PM

They want me to find the sample mean for profits as a percentage of assets. I have the classes and frequency. So far I've tried the sum of xf divided by n, but that didn't work. Any help ?

EDIT: I figured showing is easier than telling. I also used 18.4 to calculate s squared and s, but if I use that for the mean, it says it's wrong.
