One hundred pregnant women and their developing fetuses were monitored over the course of pregnancy in a study designed to compare the average weight gain of a woman during pregnancy with the average weight gain of the developing fetus.

Using Table 1-2, how does the mother's rate of weight gain compare with the rate of weight gain of the developing fetus?

Referring to Table 1-2, during the last 16 weeks of pregnancy, how does the mother's total weight gain compare with the total weight gain of the developing fetus?
