The best method to answer the statistical question "Does drinking one cup of chamomile tea before bed reduce the time it takes men aged 25-35 to fall asleep?" is:
**B. Experiment**
In this case, an experiment would involve randomly assigning participants (men aged 25-35) to two different groups: one group would drink chamomile tea before bed, while the other group would drink a placebo or no tea. This design allows for a controlled comparison of the time it takes to fall asleep between the two groups, helping to establish a causal relationship.
Observational studies (A) would not control for confounding variables, and surveys (C) would primarily gather self-reported data without establishing a cause-effect relationship. Therefore, an experiment is the most rigorous method for assessing the effect of chamomile tea on sleep onset time.
