In a previous year, 61% of females aged 15 years of age and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 800 females aged 15 years of age and older and finds that 464 are living alone. Is there sufficient evidence at the = 0.01 level of significance to conclude the proportion has changed? Identify the null and alternative hypotheses for this test. O-A. Ho: p=0.61 H: p>0.61 OD.
