**PsyDAG**, Friday, April 24, 2009 at 11:19amTo get P = .05, Ho needs to have μ ± 1.96 SD, Reject Ho, if value is outside that range.

P is determined by Z score = (X-μ)/SD. Look up value in "area under normal distribution" in back of your stats text.

Is "that" your SD?

I hope this helps. If not, repost with more questions. Thanks for asking.
