Question 1077014: Question 4 10.2.11-T
Test the hypothesis using the P value approach. Be sure the verify the requirements of the test.
H0: p=.77 versus H1: p is not equal to .77
n=500,x=380, alpha a=.05
I'm having a hard time figuring out what the p value is

You can put this solution on YOUR website! Test the hypothesis using the P value approach. Be sure the verify the requirements of the test.
H0: p=.77
H1: p is not equal to .77
n=500,x=380, alpha a=.05
sample proportion = 380/500 = 0.76
=====
Test Statistic:: z(0.76) = (0.76-0.77)/sqrt[0.77*0.23/500] = -0.5313
---
P-value = 2*P(z < -0.5313) = 2*normalcdf(-100,-0.5313) = 2*0.2976 = 0.5952
-----
Since the P-value is greater than 5%, fail to reject Ho.
