The average normal infant born in the United States weighs between 12 and 14 pounds at the age of three months. Therefore, if a three-month-old child weighs only 10 pounds, its weight gain has been below the United States average.
Which of the following indicates a flaw in the reasoning above?
Weight is only one measure of normal infant development.
Some three-month-old children weigh as much as 17 pounds.
It is possible for a normal child to weigh 10 pounds at birth.
The phrase "below average" does not necessarily mean insufficient.
Average weight gain is not the same as average weight.
