The test statistic in a right-tailed test is z= 1.71. 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. The P-value is (Round to three decimal places as needed.) This P-value V sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because it is V the significance level. b.

A two-sided hypothesis test is being conducted for testing the mean of a normal distribution at the 90% level. The hypothesized mean value is 60 whereas the true mean is 61 with the variance being equal for both the hypothesized and real distributions at the value of 12.20. The sample size is 9. What are the values of the following in the asked order: Pr(Failing to reject the null hypothesis when it is false), Pr(Rejecting the null hypothesis when it is true), the power of the hypothesis test?
