low-birth-weight babies - Researchers in Norway an-
alyzed data on the birth weights of 400,000 newborns
over a 6-year period. The distribution of birth weights
is Normal with a mean of 3668 grams and a standard
deviation of 511 grams.Babies that weigh less than
2500 grams at birth are classified as “low birth weight.”


(a) What percent of babies will be identified as low birth
weight?


(b) Find the quartiles of the birth weight distribution.

Birth weight, in grams, of newborn babies are normally distributed with a mean of 3290 grams and a standard deviation of 520 grams. Find the percentage of newborns that weigh between 3000 and 4000 grams. Consider again the birth weights of newborn babies, where the mean weight is 3290 grams and the standard deviation is 520 grams. Find the weight, in grams, that would separate the smallest 4% of weights of newborns from the rest.
