In a previous year, 59% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 450
females aged 15 and older and finds that 258 are living alone. Is there sufficient evidence at the a = 0.1 level of significance to conclude the proportion has changed?
