The test statistic of $z=2.29$ is obtained when testing the claim that $p\ne 0.387$.
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 $\alpha =0.10$, should we reject ${\mathrm{H}}_0$ or should we fail to reject ${\mathrm{H}}_0$ ?

a. This is a test.
b. $P$-value $=$ (Round to three decimal places as needed.)
c. Choose the correct conclusion below.
A. Reject ${\mathrm{H}}_0$. There is sufficient evidence to support the claim that $p\ne 0.387$.
B. Fail to reject ${\mathrm{H}}_0$. There is sufficient evidence to support the claim that $p\ne 0.387$.
C. Reject ${\mathrm{H}}_0$. There is not sufficient evidence to support the claim that $p\ne 0.387$.
D. Fail to reject ${\mathrm{H}}_0$. There is not sufficient evidence to support the claim that $p\ne 0.387$.
