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
