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?
