One of the best indicators of the health of a baby is his/her weight at birth. In the United States, mothers who live in poverty generally have babies with lower birthweight than those who do not live in poverty. 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?

	a.
	b.
	c.
	d.
