Answer #1

a. Hypothesis: Vs  

The test is right-tailed test.

b. The p-value is ,

p-value=

; From standard normal distribution table

c. Decision : Here , p-value =0.0158<0.05

Therefore , reject the null hypothesis at 0.05 significance level.

Conclusion : A. Reject Upper H 0. There is sufficient evidence to support the claim that p>0.2
