Homework Help: AP Statistics

Posted by Alex on Wednesday, September 2, 2009 at 8:30pm.

Hi, we just started density curves in AP Stats, and I am a little confused about one of the concepts.

It keeps saying that a density curve has to have an area equal to 1 below it...

1 of what?

I don't understand how you figure out if the area of your curve is 1, or what unit this "1" is in...

Sorry, and thanks!
