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 of abnormalities. 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 reasonable evidence.) Complete parts a through f. Assume the independence assumption is met. a) Write appropriate hypotheses. Let p be the proportion of children with genetic abnormalities. Choose the correct answer below. O A. Ho: p= 0.06 vs. Ha: p0.0698 O D. Ho: p= 0.06 vs. Ha: p>0.06 O E. Ho: p = 0.0698 vs. Ha:p#0.0698 O F. Ho: p= 0.0698 vs. Ha: p<0.0698 b) Check the necessary assumptions. Which of the following are satisfied? Select all that apply. O A. There are more than 10 successes and 10 failures. O B. The…
