In a previous year, 51% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 350 females aged 15 and older and finds that 169 are living alone. Is there sufficient evidence at the a = 0.05 level of significance to conclude the proportion has changed? Because no (1 - Po ) = 10, the sample size is 5% of the population size, and the sample a random sample, all of the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.)
