Newborn babies: A study conducted by the Center for Population Economics at the University of Chicago studied the birth weights of 628 babies bom in New York. The mean weight was 3026 grams with a standard deviation of 860 grams. Assume that birth weight data are approximately bell-shaped. Part I of 3 (a) Estimate the number of newborns whose weight was less than 3886 grams. Approximately of the 628 newborns weighed less than 3886 grams. Part 2 of 3 (b) Estimate the number of newborns whose weight was greater than 1306 grams. Approximately of the 628 newbornseighed more than 1306 grams. Part 3 of 3 (c) Estimate the number of newborns whose weight was between 3026 and 4746 grams.
