Final answer:
The expected minimal output for a child weighing 15 pounds over 6 hours would be approximately 0.0 pounds.
Step-by-step explanation:
The expected minimal output for a child who weighs 15 pounds over a 6-hour period can be estimated based on the average weight gain of neonates. According to the provided information, a child that just born weighs 12 pounds and increases to 28 pounds over a year. This means that in 6 hours, the child would gain approximately 0.006 pounds (28 - 12 = 16 pounds gained in a year, 16/365 = 0.0438 pounds gained per day, 0.0438/24 = 0.001825 pounds gained per hour, 0.001825 * 6 = 0.01095 pounds gained in 6 hours). Rounding to the tenth's place, the expected minimal output for a child who weighs 15 pounds over 6 hours would be approximately 0.0 pounds.
