Ok if I set this up as z= x- mean / @ suppose to be standard mean I come up with 4 as a zscore which isn't on the chart I am lost at what I should be doing... is there something else that I should do...

I am assuming I would be looking at the column c of the table because its above the z score

4. What is the percentile rank of a raw score of 50?

Im confused at how I should be setting this problem up to start it. I end up knowing what to do once I start it..

Column b here

Any help you guys could give me would be great
