AP Stats Tomorrow!!!

<p>i thought it was wednesday...lol</p>

<p>have you studied? i haven't :( i have the whole barron's to cover today</p>

<p>yeah i studied...i'm just going to do practice test from barron's tonight and tomorrow morning (i don't have to go to school until 12 since that's when the exam starts). </p>

<p>This is a self study for me; I've read all of a barron's and part of a textbook...</p>

<p>yay...uhm..</p>

<p>so what is meant by a 95% confidence interval?</p>

<p>"we are 95 confident that the true mean of the population of _____ is between (lower bound) and (upper bound)"</p>

<p>how accurate are the barrons practice tests? how would you rate them in terms of difficulty compared to the real thing?</p>

<p>can someone tell me what score out of 5 this performance on a barrons test would be..
