A key study in the 1990s examined the effectiveness of supplements in preventing congenital malformations. Researchers selected 4,000 pregnant women in their first trimester and measured their daily dosage of vitamin D supplements. Out of the 4,000 women, 78% reported taking at least 10 micrograms of vitamin D each day. Among these women, 1.3% had congenital malformations, compared to 2.3% of the 22% who did not take sufficient amounts of vitamin D. This difference yielded a p-value of less than 0.05 in a hypothesis test. What conclusion can be drawn from this experiment?
