Low birth weight is a term used to describe babies who are born weighing less than 5 pounds, 8 ounces (2,500 grams). Some studies suggest that women who have their first baby at age 35 or older are at increased risk of having a baby with low birth weight. A 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 mean weight of the 125 newborns was 3111.4 grams with a standard deviation of 501.3 grams. Is there evidence to suggest low birth weight for newborns who are the first child for women over the age of 35? What type of error might have been made?
