Best ResponseYou've already chosen the best response.0Statistics, correct? You need to use your graphing calculator and do this: finding zscore, you use invnorm (under distr button... on my calc, the TI84 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:)
