The average birth weight for babies at a certain hospital is 6.98 pounds with a standard deviation of 0.52 pounds. Assume that the distribution of birth weights is normal. (a) What is the probability that a baby born at this hospital has a weight between 6.25 and 7.5 pounds? (b) What percentage of babies born weigh at least 8.25 pounds? (c) Unusually small babies are given special attention. If the hospital defines “unusually small” as having a birth weight below the fifth percentile, then what is the maximum birth weight that merits special attention?
