Baby Weights Three-month-old Benjamin Chance weighed 13.3 pounds. The national average for the weight of a 3-month-old baby is 12.5 pounds, with a standard deviation of 1.5 pounds. Round your answers to two decimal places. a. Determine the z- score for Benjamin's weight at age 3 months, and write a sentence interpreting the score. Z-score equals = 0.53 Benjamin was ________%_ standard deviations above the average weight. b. For a 6-month-old, the national average weight is 17.25 pounds, with a standard deviation of 2.0 pounds. Determine what Benjamin's weight would have been at the age of 6 months, in order for him to have the same z-score at 6 months that he had at 3 months. ________________________
