All I know is that it is used when there is a Gaussian Distribution.......

How do I exactly use it?

I know it is Q( (x - expectation)/variance)).

You search for your Q(x) [yes, it just turns to x] on the table and boom, it gives you your answer. ...

but the value that Q takes is never on the table......

Maybe (x - expectation)/variance) is not the value that Q takes?

I am so lost😕

 
Uhh, are we talking stats here? I could help you but that was so last year. Just use the TI-89 Stats app and it'll tell you everything.

stats, you're right. I do not think the 89 will help. Basically, I am given the function. It is gaussian, so you have to use this function. if you do the integration, you'll be up all night doing several different techniques just to get the answer and chances are teh answer will be wrong.
