can anyone explain to me how to find p value from a printout?

[sinful]

I'm studying for my final and just can't seem to find this in the text. If anyone could help out that would be great. here is a sample problem

one - Sample proportion test

sample size 1200
successes 675
proportion 0.56250

null hypothesis: P = 0.54
Alternative Hyp: P > 0.54

Difference 0.02250
Standard Error 0.01432
Test Statistic Z = 1.56

95% confidence Interval
(0.53443, 0.59057)


again, I'm trying to figure out exactly how to find the p-value. I didn't think it was to difficult, I'm just having a brain meltdown for some reason. Also, what does the p-value represent?

thanks all

nevermind I figured it out. You have to use the z = 1.56(.4406) then subtract

.5-.4406 = .0594

'p' is the true value of success proportion in the population.
You have to estimate 'p' by the sample proportion i.e. 0.5625. The sample proportion is an unbiased estimator of 'p'.
