Assume that full-term babies' weights are Normally distributed with a mean of 3500 grams and a standard deviation of 600 grams. What weights make up the middle 50% of all full-term babies' weights? Round your answers to the nearest gram (the ones place). The low end of the range is grams and the high end is grams.
