According to the National Vital Statistics, full-term baby’s birth weights are approximately normal distributed with a mean of 7.5 lb and a standard deviation of 1.1 lb. Some physicians believe that a birth weight of 5.5 lb or less is dangerous. If there were 600 full-term babies born at a hospital in 2010, how many of them would you expect to weigh 5.5 lb or less?
