Newborn babies: A study conducted by the Center for Population Economics at the University of Chicago studłed the birth weights of 725 babies born in New York. The mean weight was 3166 grams with a standard deviation of 884 grams. Assume t birth weight data are approximately bell-shaped. Part 1 of 3 (a) Estimate the number of newborns whose weight was less than 4934 grams. Approximately of the 725 newborns weighed less than 4934 grams. Part 2 of 3 (b) Estimate the number of newborns whose weight was greater than 2282 grams. Approximately of the 725 newborns weighed more than 2282 grams. Part 3 of 3 (c) Estimate the number of newborns whose weight was between 3166 and 4050 grams. Approximately of the 725 newborns weighed between 3166 and 4050 grams.
