2. Babies at Risk Weights of newborn babies in the United States are normally dis tributed with a mean of 3420 g and a standard deviation of 495 g (based on data from "Birth Weight and Prenatal Mortality " by Wilcox et al., Journal of the American Medical Association , Vol 273 , No. 9). a. A newborn weighing less than 2200 g is considered to be at risk, because the mor tality rate for this group is at least 1%. What percentage of newborn babies are in the " atriskā category? If the Chicago General Hospital has 900 births in a year, how many of those babies are in the riskcategory? b . If we redefine a baby to be at risk if his or her birth weight is in the lowest 2 %, fino the weight that becomes the cutoff separating at- risk babies from those who are no at risk c . If 16 newborn babies are randomly selected , find the probability that their mea weight is greater than 3700 g . d. If 49 newborn babies are randomly selected , find the probability that their mea weight is between 3300 g and 3700 g . Lo
