The test statistic of $z= 1.13$ is obtained when testing the claim that $p>0.2$.
a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed.
b. Find the P-value.
c. Using a significance level of $\alpha= 0.05$, should we reject $\mathrm{H}_{0}$ or should we fail to reject $\mathrm{H}_{0}$ ?

a. This is a $\square$ test.
b. P-value $=\square$ (Round to three decimal places as needed.)
c. Choose the correct conclusion below.
A. Fail to reject $\mathrm{H}_{0}$. There is sufficient evidence to support the claim that $p>0.2$.
B. Reject $\mathrm{H}_{0}$. There is not sufficient evidence to support the claim that $p>0.2$.
C. Fail to reject $\mathrm{H}_{0}$. There is not sufficient evidence to support the claim that $p>0.2$.
D. Reject $\mathrm{H}_{0}$. There is sufficient evidence to support the claim that $p>0.2$.

Step 1
Since the claim is that $p$ is greater than 0.2, this is a right-tailed test.
Step 2
Therefore, the P-value is $0.1302$.
From the standard normal distribution table, the corresponding area is approximately 0.1302.
Final Answer
a. This is a right-tailed test. b. P-value $= 0.1302$ c. Fail to reject $\mathrm{H}_{0}$. There is not sufficient evidence to support the claim that $p>0.2$.
