(f) Data from the National Vital Statistics Report indicate that there were 3,880,894 births in the United States in
1997. A total of 291,154 babies were of low birth weight, while 2,552,852 babies weighed between 3000 and 4000
grams. Compute the observed proportions in each of these two groups, and comment on how well the normal
calculations approximates these values.
