The average birthweight for babies born in the U.S. is approximately 3300 grams,
whereas the average birthweight for women living in poverty is 2800 grams.
Recently, a hospital introduced a new prenatal care program to increase the
birthweight of babies born in the hospital. In the first year, 25 mothers, all of
whom live in poverty, participated in this program. Data reveals that the babies
born to these women had a birthweight of 3075 grams, with a standard deviation of
500 grams. Which of the following gives the appropriate setup for the H0 and H1 in
this experiment?
