Question
Although many new moms will nurse their new babies in the beginning, the Pediatrics Association
believes that 50% of moms are still nursing their babies by the time the babies are six months old.
The La Leche Society believes that this proportion is less than 50% and thus believes more educa-
tional information should be given to new moms to encourage the mothers to nurse for the first
year of their child's life. A random sample of 425 new moms was obtained and 200 were still nurs-
ing their child at six months of age. At the 2.5% significance level, what conclusion can be reached?
