It the 1980s, it was generally believed that congenital abnormalities affected about 7% 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 394 randomly selected children and found that 30 of them showed signs of an abnormality. Is this 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=0.0761 vs. HA: p>0.0761 O c. Ho: p=0.0761 vs. HA: P<0.0761 O E. Ho: p=0.07 vs. HA: p>0.07 B. Ho: p=0.07 vs. HA: P = 0.07 D. Ho: p=0.07 vs. HA: P <0.07 Ho: p=0.0761 vs. HA: P# 0.0761 OF.
