In a previous year, 56% of females aged 15 years of age and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 700 females aged 15 years of age and older and finds that 406 are living alone.

What is th enull and alt. hypothesis? the test statistic? the P-value? What is the conclusion?

In a previous year, 56% of females aged 15 years of age and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 700 females aged 15 years of age and older and finds that 406 are living alone. Is there sufficient evidence at the x = 0.05 level of significance to conclude the proportion has changed? Identify the null and alternative hypotheses for this test. O A. Ho: p=0.56 H₁: p=0.56 Ⓒ D. Ho: p *0.56 H₁: p=0.56 Find the test statistic for this hypothesis test. Z= (Round to two decimal places as needed.) OB. Ho: p=0.56 H₁: p<0.56 O E. Ho: p=0.56 H₁: p > 0.56 (...) OC.
