Document Summary
Unit 5 estimation and tests of hypotheses for two or more populations. In unit 4, we began a discussion of the field of statistical inference through problems involving confidence interval estimates and hypotheses tests about the mean and proportion for a single population. After completing unit 5, you will be able to construct confidence interval estimates and conduct tests of hypotheses that can apply to a wide range of real-world situations. As an example, if you are an owner of a chain of retail clothing stores, you might compare the average dollar sales per square foot of retail space achieved at each of your different store locations. Or, you may be part of a medical research team comparing the proportion of patients that respond positively to alternative treatments for a serious disease. As a counselor at a large university, you might need to test the effectiveness of a new examination writing strategy on a cohort of freshman students.
