thank you very much in advance!!!

possible In a previous year, 55% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 700 females aged 15 and older and finds that 380 are living alone. Is there sufficient evidence at the a = 0.05 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 satisfied. gra (Round to one decimal place as needed.) Identify the null and altemative hypotheses for this test. HD : versus Hy (Type integers or decimals, Do not round.) Find the test statistic for this hypothesis test. Zo = (Round to two decimal places as needed.) Determine the P-value for this hypothesis test. es P-value= (Round to three decimal places as needed.) State the conclusion for this hypothesis test. Since the P-value is than a, Ho. There sufficient evidence at the or = level of significance to conclude that the proportion of females aged 15 and older who are living alone has changed. (Type an integer or a decimal. Do not round.)
