In the 1980s it was generally believed that congenital abnormalities affected about 5% of the 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 384 children and found that 46 of them showed signs of an abnormality. Is this strong evidence that the risk has increased? (Consider a p-value of around 1% to represent strong evidence) A) Write appropriate hypotheses. B) Check the necessary assumptions. C) Perform the mechanics of the test: Name the test, give formula and compute test statistic, sketch and label a picture, compute the p-value. D) Explain carefully what the p-value means in this context. E) What is your conclusion? F) Do environmental chemicals cause congenital abnormalities? Why or why not?
