If z scores are calculated z=(x-x bar) / standard deviation..
What is the corresponding x if the mean (x bar) is 200, the standard deviation is 20, & z = 1.5. I hate math :(

OK, even though I need help I know that "56" is not the right answer. I'd really appreciate some legitimate help, all.

I'm sorry, I don't know the answer. But I can tell you this. I took statistics a couple terms ago, and I actually referred to it as "sadistics". Get a really good calculator like a TI-83 and it will be able to find all that stuff for you. Good luck.
