If the individual observations have the N(mu, theta) distribution, then the sample mean (x bar) of n independant observations has the N(mu, theta/ Square root of n) distribution.
Yeah. Cuz I have no idea and I'm about to go face my doom in.... 10 minutes.
I'm not even kidding.... I have been going to class, but this shit is so boring, no joke, I don't even know what theta is, numerically. I think it might be the standard of deviation of a set of data... but even if that was it... I DONT KNOW WHAT THE STANDARD OF DEVIATION IS OR HOW TO COMPUTE IT. This will be pathetic and possibly my demise.
Guess I'll just go get it over with.
