A key study in the 1990s exаmined the effectiveness оf supplements in preventing cоngenitаl mаlfоrmations. Researchers flipped a coin to decide whether women planning a pregnancy were given either a combined vitamin and mineral supplement or a mineral-only supplement to take daily for at least one month before conception. Out of 2,104 births in the vitamins and minerals group, 1.3% had congenital malformations, while 2.3% of the 2,052 births in the mineral-only group had congenital malformations which yields a p-value less than 0.05 on a hypothesis test. What conclusion can be drawn from this experiment?
