Your friend concerns about her baby's weight whether it is too big at his age. Kevin, your friend's baby, is 10-month old and weighs 12 kilograms. She is reading one article that the researchers classified the babies' weights based on CDC growth charts, which compare a baby's growth to a standardized growth curve. Kids in the 95th percentile of weight were categorized as "obese," while kids in the 85th to 95th percentile were counted as "at-risk," similar to the adult category of "overweight". She is wondering whether Kevin's weight is below or greater than the 95th percentile and whether he is at-risk. You looked on the Internet and found the CDC growth charts for a baby boy below. The first column is age in months from 0 to 15 months. The second to tenth column are z-scores of baby boy's weights in the population (-2,-1.5, -1, -0.5, 0, 0.5, 1, 1.5, 2). The numbers in the blue box are baby boys' weights (in kgs) given his age.
