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 1% 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 = -1.78. The P-value is (Round to three decimal places as needed.) At the 1% significance level, the data the obtained P-value is b. The test statistic in a left-tailed test is z = 1.64. The P-value is (Round to three decimal places as needed.) At the 1% significance level, the data the obtained P-value is sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because the significance level. sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because the significance level.
