In Exercises 9 –14, find the P@value for the hypothesis test with the standardized test statistic z. Decide whether to reject H0 for the level of significance a. 9. Left-tailed test 10. Left-tailed test z = -1.32 z = -1.55 a = 0.10 a = 0.05 11. Right-tailed test 12. Right-tailed test z = 2.46 z = 1.23 a = 0.01 a = 0.10 13. Two-tailed test 14. Two-tailed test z = -1.68 z = 2.30 a = 0.05 a = 0.01

Finding a P-Value In Exercises 9-14, find the P-value for the hypothesis test with the standardized test statistic z. Decide whether to reject H0 for the level of significance ̑. 9. Left-tailed test z = -1.32 ̑ = 0.10

In Exercises, we have given the value obtained for the test statistic, z, in a one-mean z-test. We have also specified whether the test is two tailed, left tailed, or right tailed. Determine the P-value in each case and decide whether, at the 5% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. Left-tailed test: a. z = -0.74 b. z = 1.16

In Exercises 9.63–9.68, we have given the value obtained for the test statistic, z, in a one-mean z-test. We have also specified whether the test is two tailed, left tailed, or right tailed. Determine the P-value in each case and decide whether, at the 5% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. 9.67 Two-tailed test: a. z =−1.66 b. z = 0.52
