Test the hypothesis using the p value approach. Be sure to verify the requirements of the test.
H0:p=0.6 versus H1:p >0.6
N= 200; x= 125, a= 0.05
Is np0(1-p0) > 10?
P-value?

Solution
H0:p=0.6 versus H1:p >0.6
Right tailed test.
np0 = 200(125/200) >10
np0q0 = 200(125/200) (75/200) = 46.875>10
-------------------------------------------------
p0 for sample = 0.625
Std error of sample = root of 0.6(0.4)/200
= 0.0346
p0-p = 0.025
Hence
z statistic = 0.025/0.0346
= 0.7225
p value = 0.2350
As p >0.05 accept null hypothesis
p=0.6 is statistically evident.
