what is the p value 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 toan increase in the incidence of abnormalities. A recent study examined 426 randomly selected children and found that 34 of them showed signs of an abnormality. Is this strong evidence that the riskincreased? (We consider a P-value of around 5% to represent reasonable evidence.) Complete parts a through f. Assume the independence assumption is met.hasa) Write appropriate hypotheses. Let p be the proportion of children with genetic abnormalities. Choose the correct answer below.O A. Ho: p=0.07 vs. HA: P = 0.07B. Ho: p=0.07 vs. HA: p > 0.07O C. Ho: p=0.0798 vs. HA: p>0.0798O D.
