Question

In a previous year, 52% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 750 females aged 15 and older and finds that 397 are living alone. Is there sufficient evidence at the a=0.1 level of significance to conclude the proportion has changed? less than 5% of the population size, and the sample is given to be random the requirements for Because np.(1-P) = 187.2 10, the sample size is testing the hypothesis are satisfied (Round to one decimal place as needed.) Identify the null and alternative hypotheses for this test. Ho versus H. (Type integers or decimals. Do not round.)

Answer 1

Ho:p = 0.52

H:P = 0.52
