Review Test: Test 3 Points: 0.94 of 1 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 simple of 650 females aged 15 and older and finds that 35 Is there sufficient evidence at the a = 0.01 level of significance to conclude the proportion has changed? Because npp (1 -Po) = 160.9 > 10, the sample size is less than 5% of the population size, and the sample is a random sample, all of the requirements for testing the hypothesis are satisfied (Round to one decimal place as needed.) Identify the null and alternative hypotheses for this test Ho: p = 0.55 versus Hy: p # 0.55 (Type integers or decimals. Do not round.) Find the test statistic for this hypothesis test. 20 = -0.43 (Round to two decimal places as needed.) Determine the P-value for this hypothesis test. P-value = 0.665 (Round to three decimal places as needed.) State the conclusion for this hypothesis test. Since the P-value is greater than a, do not reject Ho There is not sufficient evidence at the a= 0.01 level of significance to conclude that the proportion of females aged 15 and older who are living alone ha (Type an integer or a decimal.
