The American Statistician, Nov 1999, 53:4). However, they also found that when infants born outside of the "typical" 37-43 weeks and infants born to mothers with a history of diabetes are excluded, the birth weights of the remaining infants do follow a Normal model with mean u = 3432 g and standard deviation o = 482 g. The following questions refer to infants born from 37 to 43 weeks whose mothers did not have a history of diabetes. Compute the z-score of an infant who weighs 3572 g. (Round your answer to two decimal places.) Approximately what fraction of infants would you expect to have birth weights between 2440 g and 3740 g? (Express your answer as a decimal, not a percent, and round to three decimal places.) Approximately what fraction of infants would you expect to have birth weights above 3740 g? (Express your answer as a decimal, not a percent, and round to three decimal places.) A medical researcher wishes to study infants with low birth weights and seeks infants with birth weights among the lowest 8%. Below what weight must an infant's birth weight be in order for the infant be included in the study? (Round your answer to the nearest gram.)
