This Question: pts Question Help In a previous year, 01% 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 300 females aged 15 years of age and older and finds that 195 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...
