In 2002 a national vital statistics report indicated that about 3.7% 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 14 sets of twins were born to 598 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 O No State the null and alternative hypotheses. Choose the correct answer below. O A. Ho: p=0.037 HA: P >0.037 O B. Ho: p=0.037 HA: P<0.037 c. Ho: p=0.037 HA: P = 0.037 OD. The assumptions and conditions are not met, so the test cannot proceed. Determine the z-test statistic. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. z (Round to two decimal places as needed.)
