You know, where it says if you're online, how do you change it?

I dunno what you're talking about. You mean the little picture? I think it's a rank thing or sumtin.

I really hate how I've made more than 12,000 posts here. Thankfully this swaying, moving Chandelure makes it all worth it.

o hai I need statistics help D:

How do I find what sample size is needed so that a certain proportion (like 95%) of all samples are within a certain range of the true mean (like one standard deviation or something) if the data is normally distributed?  I know I have to work backwards somehow, but...???????

ooh nevermind I got it

.95/2 = .475
.5000 - .475 = .025
.5000 + .475 = .975
-1.90 < z < 1.90
(19.22-18.22)/(11.399/(n)) = 1.9
1/(11.399/(n)) = 1.9
(n)/11.399 = 1.9
(n) = 21.6581
n  469


I feel so complete olol...all question marks except for the last one are radicals, last one is approximately equal sign (squiggly)

That scares me.
