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? Because npo (1- Po) = 108.9 > 10, the sample size is (Round to one decimal place as needed.) less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis are satisfied. Identify the null and alternative hypotheses for this test. Họ: || versus H1: (Type integers or decimals. Do not round.)
