Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method.

Use either the T Calculator or the Normal Calculator to compute the P-value of the following test statistics.

(a) The test statistic in a two-tailed is z = 1.39. Round to four decimal places.

(b) Find the P-value for a right-tailed test with n = 27 and test statistic t = 1.502. Round to four decimal places.

Answer 1

Answer #1

(a) The test statistic is two-tailed

the value of test stat is z = 1.39.

p value is 0.1645

(b) the test is right-tailed test

n = 27 and df = 26

test statistic t = 1.502.

p value is.0726
