Hi . I really need help with this problem. Results of a 1996 American Medical Association report about the infant mortality rate for twins carried for the full term of a normal pregnancy are shown below, broken down by the level of prenatal care the mother had received. http://img98.exs.cx/img98/836/untitled138.jpg A. Should the overall rate be the average of the other 3 rates? My answer - Yes B. Do these results indicate that adequate prenatal care is important for pregnant women? My answer- No C. Do these results suggest that a women pregnant with twins should be wary of seeking too much medical care? My Answer- Yes Is this correct? Any help would be greatly appreciated.
