In Exercises 9.55-9.60, we have given the value obtained for the test statistic, Z, in one mean Z-test. We have also specified weather the test is two tailed, left tailed right tailed. Determine the P-value in each case and decide weather, at the 5% significance level, the data provide sufficient evidence to reject the mull hypothesis in favor of the alternative hypothesis. 9.55 Right-tailed test: a. Z = 12.03 b. Z = -0.31
