In a previous year, 61% 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 273 are living alone. Is there sufficient evidence at the x = 0.01 level of significance to conclude the proportion has changed? Because npo (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 (Round to one decimal place as needed.) satisfied.
