Babies born weighing 2500 grams (about 5.5 pounds) or less are called low-birth-weight babies, and this condition sometimes indicates health problems for the infant. The mean birth weight for children born in a certain country is about 3494 grams (about 7.7 pounds). The mean birth weight for babies born one month early is 2632 grams. Suppose both standard deviations are 490 grams. Also assume that the distribution of birth weights is roughly unimodal and symmetric. Complete parts a through c below. a. Find the standardized score (z-score), relative to all births in the country, for a baby with a birth weight of 2500 grams. z = 2.03 (Round to two decimal places as needed.) b. Find the standardized score for a birth weight of 2500 grams for a child born one month early, using 2632 as the mean. Z= (Round to two decimal places as needed.)
