Test the hypothesis using the​ P-value approach. Be sure to verify the requirements of the test.
Upper H0​: p=0.3 versus Upper H1​: p>0.3
n=200​; x=70​, alphaα=0.01
sample proportion = 70/200 = 0.35
----
z(0.35) = (0.35-0.3)/sqrt[0.3*0.7/70] = 0.9128
----
p-value = P(z > 0.9128) = normalcdf(0.9128,100) = 0.1807
---
Conclusion:: Sine the p-value is greater than 1%, fail to reject Ho.
