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 part (a) and (b), determine the P-value and decide whether, at the 10% 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= - 1.38. The P-value is 0.084 . (Round to three decimal places as needed.) At the 10% significance level, the data provides sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because the obtained P-value is less than the significance level. b. The test statistic in a left-tailed test is z= 1.89. The P-value is. (Round to three decimal places as needed.)

A one-sided hypothesis test is to be performed with a significance level of 0.05. Suppose that the null hypothesis is false. If a significance level of 0.01 were to be used instead of a significance level of 0.05, which of the following would be true? A B O E Neither the probability of a Type Il error nor the power of the test would change. Both the probability of a Type II error and the power of the test would decrease. Both the probability of a Type Il error and the power of the test would increase. The probability of a Type II error would decrease and the power of the test would increase. The probability of a Type Il error would increase and the power of the test would decrease.
