The U.S. Census Bureau reported in 2002 that, for people 18-24 years old, the mean annual income for people who never married was $21,539 and for married people was $19,321. Suppose that this information came from a survey of 100 people from each group. Is this evidence that people who never married earn more than people who married? What type of hypothesis test should you do? 2-sample test (proportions) matched pairs test Oz-test for means O t-test for means 2-sample test (means) z-test for proportions
