The vаlue оbtаined fоr the test stаtistic, z, in a оne-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 two-tailed test is z=−1.29. The P-value is [p] (Round to three decimal places as needed.) At the 5% significance level, the data [a] (does not provide/provides) sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because the obtained P-value is [b] (less than/greater than) the significance level. b) The test statistic in a two-tailed test is z = 0.45. The P-value is [q] (Round to three decimal places as needed.) At the 5% significance level, the data [c] (does not provide/provides) sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because the obtained P-value is [d] (less than/greater than) the significance level.
