4. Economists often track employment 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 winter of 2020/2021, 12% of Americans were "underemployed." The mayor of Miami Beach wants to show the Federal Government that the situation is worse in his town than it is in the rest of the country; the mayor is hoping to get awarded Federal aid to help his budget deficit caused by high "underemployment".

Do the data give convincing evidence that the proportion of underemployed in Miami Beach is higher than elsewhere in the country?
