A study conducted by the Center for Population Economics at the University of Chicago studied the birth weights of 687 babies born in New York. The mean weight was 3008 grams with a standard deviation of 896 grams. Assume that birth weight data are approximately bell-shaped. Estimate the number of newborns who weighed between 1216 grams and 4800 grams. Round to the nearest whole number. The number of newborns who weighed between 1216 grams and 4800 grams is what?
