For Canadian single full term births, the weight of the newborn is normally distributed with mean 3685g and standard deviation 485g. a) Find the probability that a Canadian newborn weighs between 3400g and 3950g b) The lowest 20% of all births are considered underweight. Find the weight below which a baby is considered underweight (i.e. find the 20th percentile) c) In a given week a maternity ward has 40 births. Find the probability that the mean birth weight for these babies is more than 3900g.
