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.
