The value obtained for the teststatistic, z, in aone-mean z-test is given. Whether the test is twotailed, lefttailed, or right tailed is also specified. For parts(a) and(b), determine theP-value and decidewhether, at the 10% significancelevel, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis.

a. The test statistic in aright-tailed test is z=1.02.

TheP-value is

0.155

(Round to three decimal places asneeded.)

At the 10% significancelevel, the data does not provide

sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because the obtainedP-value is greater than

the significance level.

b. The test statistic in aright-tailed test is z=2.18.

TheP-value is?

.
