how do I find what 96% confidence is on the Standard Normal Distribution chart?
what is a SND chart?
my first thought is that it is what I am used to calling a ztable, but i cant be sure
That is another name for it.
ok, then the other bad news is that there are different tables based upon what different authors feel is more intuitive so they take measurements from different places .... do you have the ztable with you?
if not, this one looks readable to me http://rchsbowman.wordpress.com/2009/12/01/statistics-standard-normal-distribution-table/
a confidence interval is usually divide about the mean, half of it is to one side and the other half on the other side. what is 96/2?
I do have that chart 96/2 would be 48 where do I go from there?
this tells us how far away from 50 we need to be; the value of the mean is 50 and we want to be half on each side of it 50 + 48 = 98 look in the field for the closest value to .9800
Iate it I understand it when I 'm in class then I get home and I totally am lost.
