I need simple help for a documentary.


I've search a long time for this place, sure hope I can find some help.

I'm doing a feature documentary where three concrete wall samples showed the top steel from 15 to 14 inches below the top of the wall. The specifications call for the steel to be 2 inches below the top and all the walls should have been installed uniformily. Analytically you could say there were 9 different wall sections total. What would be my probability or assurance that the other walls wouldn't be within specification (2 inches below the top)?

Thanks in advance and I'll also give a credit at the end of my film.
