# Question: Two tailed test a z 3 08 b z 2 42 We have

Two-tailed test:

a. z = 3.08

b. z = −2.42

We have given the value obtained for the test statistic, z, in a one-mean z-test. We have also specified whether the test is two tailed, left tailed, or right tailed. Determine the P-value in each case and decide whether, at the 5% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis.
