<p>I have a couple questions for the AP Stats exam. </p>
<p>Right now I am using the Barron's book, and for the problems concerning normal curves, and their percentages based on z or t scores, they show you how to solve it using the reference tables in the back. Will we be given these reference tables on the test? If not, how do we figure it out. </p>
<p>Also, does anyone know which parts of statistics are particularly emphasized on the exam. I know you can get a list of topics from the college board, but I am wondering which ones are really key. Preferably, if anyone used the Barron's book, are there any key chapters or topics? </p>
<p>Thanks</p>
