vious year, 56% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 350 females aged 15 and older and at 202 are living alone. Is there sufficient evidence at the α = 0.01 level of significance to conclude the proportion has changed? e npo (1-Po) = 86.2 > 10, the sample size is d. d to one decimal place as needed) the null and alternative hypotheses for this test versus H₁ integers or decimals. Do not round) ▼ less than C 5% of the population size, and the sample IS a random sample, all of the requirements for testing the hypothesis are
