Based on a July 2022 Pew Research survey, overall, three-in-ten U.S. adults are single, meaning they are not married, living with a partner or in a committed romantic relationship. This year, a group of researchers select a random sample of 1,050 adults in Boston and find that 357 are single. Does the data provide convincing evidence that more than 30% of adults in Boston are single? Test the relevant hypotheses using a 5% significance level.
