<p>Hi, I'm taking AP Stats right now, and I just have a few general questions (due to the fact that I have a horrible AP stats teacher..)</p>
<p>First of all, when we're doing things like finding the least-squares regression line, binomial probability, etc, our teacher has taught us to do everything on the graphing calc. So I pretty much do not know how to calculate numbers by hand for many things (not all, but many) - Is this bad for the AP exam? Should I learn all the lengthy formulas for calculating simple values, or completely rely on my calculator? I ran in to one question where I really couldn't solve it without knowing how to solve it the fairly long way by hand, and the calculator was not much help. </p>
<p>In other words, is it bad that I rely a lot on my calculator for probability values, linear regression, etc?</p>
