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.

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?
