"One-tailed"-the alternate hypothesis is greater than direction. b. What is the decision rule? (Round your answer to 3 decimal places.) H0, when z > (Click to select) c. What is the value of the test statistic? (Round your answer to 2 decimal places.) Value of the test statistic d. What is your decision regarding H0? Do not reject Reject e. There is sufficient or insufficient evidence to conclude that the population mean is greater than 25? f. What is the p-value
