A sample of 84 observations is selected from a normal population. The sample mean is 30, and the population standard deviation is 7. Conduct the following test of hypothesis using the 0.05 significance level. H0 : μ ≤ 29 H1 : μ > 29 a. Is this a one- or two-tailed test? One-tailed test Two-tailed test b. What is the decision rule? (Round the final answer to 3 decimal places.) Reject/ Accept H0 and accept /reject H1 when z > . c. What is the value of the test statistic? (Round the final answer to 2 decimal places.) Value of the test statistic d. What is your decision regarding H0? Do not reject Reject H0. There is enough not enough evidence to conclude that the population mean is greater than 29. e. What is the p-value? (Round the final answer to 4 decimal places.)
