STAT 2023 Assignment 9 Fall 2019 due by 10pm Monday, October 28 Hypothesis Test on the Population Mean, Variance Known, Lesson 14 1. In a hypothesis test if the research question is, “Do the data indicate that the mean is different from a specific value?” then is the hypothesis test a two-tail, left-tail, or right-tail test? Two-tail 2. In a hypothesis test if the research question is, “Do the data indicate that the mean is less than a specific value?” then is the hypothesis test a two-tail, left-tail, or right-tail test? Left-tail 3. In a hypothesis test if the research question is, “Do the data indicate that the mean is greater than a specific value?” then is the hypothesis test a two-tail, left-tail, or right-tail test? Right-tail 4. What is the rejection point (the number that cuts off the rejection region) for the significance level of .10 for a right-tail Z-based hypothesis test? 1.282 5. What is the rejection point (the number that cuts off the rejection region) for the significance level of .05 for a right-tail Z-based hypothesis test? 1.645 6. What is the rejection point (the number that cuts off the rejection region) for the significance level of .01 for a right-tail Z-based hypothesis test? 2.326 7.
