Birthweight: Birth Weights of Newborns
Description
Some studies suggest that women having their first baby
at age 35 or older are at increased risk of having a baby
with a low birth weight. A medical researcher wanted to
estimate the mean weight back in the population of
newborns who are the first child for women over the age
of 35. To this end, the researcher chose a random sample
of 125 women age 35 or older who were pregnant with their
first child and followed them through the pregnancy. The
datafile linked below contains the birth weight (in
grams) of the 125 newborns (women pregnant with more than
one child were excluded from the study).format
