Suppose that a recent report from the Current Population Survey (CPS) of the United States Census Bureau states that 46% of Americans say that now is a good time to find a quality job. Cory works for the mayor's office in a medium-sized city in Texas. The mayor would like to be able to state that the proportion of people in his city are more optimistic about job prospects than people are nationwide and has asked Cory to conduct a study. To test this claim, Cory forms the following null and alternative hypotheses. Ho: p = 0.46 H₁: p > 0.46 The variable p represents the proportion of people in his city who state that now is a good time to find a quality job. The alternative hypothesis, H₁, represents his claim that the proportion of people in his city who state that now is a good time to find a quality job is greater than 46%. To see if his assumption is correct, Cory randomly selects 500 residents of his city. His results are displayed.
