CHAPTER 9

Statistical Inference: Hypothesis Testing for Single Populations

LEARNING OBJECTIVES

The main objective of Chapter 9 is to help you to learn how to test hypotheses on single populations, thereby enabling you to:

  1. Develop both one- and two-tailed null and alternative hypotheses that can be tested in a business setting by examining the rejection and non-rejection regions in light of Type I and Type II errors.
  2. Reach a statistical conclusion in hypothesis testing problems about a population mean with a known population standard deviation using the z statistic.
  3. Reach a statistical conclusion in hypothesis testing problems about a population mean with an unknown population standard deviation using the tstatistic.
  4. Reach a statistical conclusion in hypothesis testing problems about a population proportion using the z statistic.
  5. Reach a statistical conclusion in hypothesis testing problems about a population variance using the chi-square statistic.
  6. Solve for possible Type II errors when failing to reject the null hypothesis.
