The value obtained for the test statistic, z, in a one-mean z-test is given. Whether the test is two tailed, left tailed, or right tailed is also specified. For parts (a) and (b), determine the P-value and decide whether, at the 5% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. a. The test statistic in a left-tailed test is z- 0.41. The P-value is a. (Round to three decimal places as needed.) At the 5% significance level, the data provides sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because the obtained P-value is less than the significance level. b. The test statistic in a left-tailed test is z= 2.08. The P-value is (Round to three decimal places as needed.) At the 5% significance level, the data does not provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because the obtained P-value is greater than the significance level.
