<p>Can anyone provide examples for everything about inference of the mean and population because I hate reading the textbook, I just need something concise which mean straight to the poiny: the formulas and how to do the word problems that goes with it, lol even I took the AP Exam for it this year, I still don't know inference! Also, I need to know when use a z-distribution, left distribution, right distribution, t-distribution, and 2 tails distribution! Since I have a test on it next.Tuesday and if I don't do well on it, I might as well drop it! Also, when you receive your AP scores, how would show your scores to the college you apply since I don't want to pay more $ for collegeboard to send my AP scores to another college that I didn't sign for when I register to take the AP Exams?!</p>
