Statistics, correct? You need to use your graphing calculator and do this: finding z-score, you use invnorm (under distr button... on my calc, the TI-84 plus, it is option number 3.. it may be different for you though) so then you do this 2nd, VARS, invnorm and enter 0.95 you should get a graph of a sort :) hope that helps somewhat! it's a bit odd explaining stats via writing haha it's tricky but if you study the keystrokes, it will make more sense:)
