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 439 randomly selected children and found that 48 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 A. Ho:p:0.1093 vs. HA p#0.1093 C. Ho: p 0.1093 vs. HA p>0.1093 OE. Ho:p=0.1093 vs. HA pExplanation / Answer
