In 1997 a national vital statistics report indicated that about 3.1% of all births produced twins. Is the rate of twin births the same among very young mothers? Data from a large city hospital found only 13 sets of twins were born to 594 teenage girls. Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed. Are the assumptions and the conditions to perform a one-proportion z-test met? Yes No State the null and alternative hypotheses. Choose the correct answer below. O A. Ho: p=0.031 HA: P<0.031 OB. Ho: p=0.031 HA: P = 0.031 C. Ho: p=0.031 HA: P > 0.031 OD. The assumptions and conditions are not met, so the test cannot proceed.
