It the 1980s, it was generally believed that congenital abnormalities affected about 6% of a large nation's children. Some people believe that the increase in the number of chemicals in the environment has led to an increase in the incidence ofabnormalities. A recent study examined 401 randomly selected children and found that 28 of them showed signs of an abnormality. Is his strong evidence that the risk has increased? (We consider a P-value of around 5% to represent reasonableevidence.) Complete parts a through f. Assume the independence assumption is met.d) Explain carefully what the P-value means in this context. Choose the correct answer below.O A. The P-value is the chance of observing 6% of children with genetic abnormalities.O B. The P-value is the chance of observing 28 or more children with genetic abnormalities in a random sample of 401 children.Oc. The P-value is the actual percentage of children who have genetic abnormalities.O D. The P-value is the chance of observing 28 or more children with genetic abnormalities in a random sample of 401 children if 6% of children actually have genetic abnormalities.e) What's your conclusion?O A. Reject H. There is sufficient evidence that more than 6% of the nation's children have genetic abnormalities.O B. Fail to reject Hn. There is not sufficient evidence that more than 6% of the nation's children have genetic abnormalities.O C. Reject Ho. There is not sufficient evidence that more than 6% of the nation's children have genetic abnormalities.O D. Fail to reject H. There is sufficient evidence that more than 6% of the nation's children have genetic abnormalities.f) Do environmental chemicals cause congenital abnormalities?O A. No, the conclusion of the hypothesis test shows that environmental chemicals do not cause genetic abnormalities.O B. Yes, the conclusion of the hypothesis test shows that environmental chemicals cause genetic abnormalities.O C. It is unknown if environmental chemicals cause genetic abnormalities, because the hypothesis test does not indicate the cause of any changes.1.(1,1)MoreClick to select your answer(s).

There are more than 10 successes and 10 failures.O B. The independence assumption is satisfied.O C. The sample is random.O D. Less than 10% of the population was sampled.c) Perform the mechanics of the test. What is the P-value?P-value =(Round to three decimal places as needed.)d) Explain carefully what the P-value means in this context. Choose the correct answer below.O A. The P-value is the chance of observing 6% of children with genetic abnormalities.O B. The P-value is the chance of observing 28 or more children with genetic abnormalities in a random sample of 401 children.O C. The P-value is the actual percentage of children who have genetic abnormalities.(1,1)MoreClick to select your answer(s).
