**PsyDAG**, Tuesday, July 24, 2012 at 10:55amWhat level of significance are you using? P ≤ .05? P ≤ .01?

Z = (score-mean)/SD

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportions related to the Z scores. For a one-tailed test, find Z with .05, but with a two-tailed test, look for Z with .025. If using P ≤ .01, use similar process.

**Kathy**, Saturday, July 28, 2012 at 12:57ami have the answers, but does not have the answers for the set of problems I was working on. That was one of my questions I was not completly sure of. I copied the problem word for word from the text. I did as much calculations as I knew how...it was then trying to figure out how to get the probability i think. This chapter threw me for a loop.
