Economists often track unemployment trends by measuring the proportion of people who are “underemployed,” meaning they are either unemployed or would like to work full time but are only working part-time. In the summer of 2010, 18.5% of Americans were “underemployed.” The mayor of Statsville wants to show the voters that the situation is not as bad in his town as it is in the rest of the country. His staff takes a simple random sample of 300 Statsville residents and finds that 43 of them are underemployed. What is the test statistic for this hypothesis test?
