Q4. Please complete Parts 1-5. Round answer as needed.
In 1991 a national vital statistics report indicated that about 3.6% 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 11 sets of twins were born to 424 teenage girls. Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satised before you proceed. Are the assumptions and the conditions to perform a one-proportion ztest met? 0 No Q Yes State the null and alternative hypotheses. Choose the correct answer below. 0 A. H0: p = 0.036 HA: p i 0.036 o B. HO: p = 0036 HA: p 0.030 O D. The assumptions and conditions are not met, so the test cannot proceed. Determine the ztest statistic. Select the correct choice below and, if necessary, ll in the answer box to complete your choice. O A- z = {Round to two decimal places as needed.) O B. The assumptions and conditions are not met, so the test cannot proceed. Find the P-value. Select the correct choice below and, if necessary, ll in the answer box to complete your choice. O A- Pvalue = (Round to three decimal places as needed.) O B. The assumptions and conditions are not met, so the test cannot proceed. What is your conclusion? Choose the correct answer below. 0 A. Reject H0. The proportion of twin births for teenage mothers is different from the proportion of twin births for all mothers. 0 B. Fail to reject H0. The proportion of twin births for teenage mothers is not different from the proportion of twin births for all mothers. 0 C. Reject H0. The proportion of twin births for teenage mothers is greater than the proportion of twin births for all mothers. 0 D. The assumptions and conditions are not met, so the test cannot proceedStep by Step Solution
