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

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?
