1. Birth weights of babies in the United States can be modeled by a normal distribution with mean 3250 grams and standard deviation 550 grams. Those weighing less than 2500 grams are considered to be of low birth weight. (a) Sketch a normal distribution curve and shade in the region whose area corresponds to the probability that a baby will have a low birth weight (b) Based on this shaded region, using the Empirical Rule, make an educated guess as to the proportion of babies born with a low birth weight.

![The Normal Distribution on StatCrunch
1. Birth weights of babies in the United States can be modeled by a normal distribution with mean 3250
grams and standard deviation 550 grams. Those weighing less than 2500 grams are considered to be
of low birth weight.
(a) Sketch a normal distribution curve and shade in the region whose area corresponds to
the probability that a baby will have a low birth weight
(b) Based on this shaded region, using the Empirical Rule, make an educated guess as to the
proportion of babies born with a low birth weight.
