small correction:
normalcdf(-99, marks z-score)

So the z-score would be 13.7 - 12.89/1.95?

parentheses

So (13.7 - 12.89)/1.95?

yes

normalcdf(-99, marcus' z-score)
I meant to say "Marcus", not "Mark")

Sorry, the data points below Marcus' score

what is normalcdf(-99, marcus' z-score)?

What does normalcdf mean?

do you know how to use a graphing calculator?

Umm, no... But I have a regular scientific one

I don't need one for what I'm doing... Maybe... I'm not sure lol :P

hm, did your teacher show you how to use a z-table?

Yes :) I have a z-table for positive and negative values.

I think so. Is it .65910?

yup, that's about what I got, too!
do you know what .65910 means?

I mean, do you understand what that number represents?

It means that he falls in with the scores of %65.9 of his class?
