Among 30,617 randomly selected adults, 5787 consumed herbs within the past 12 months (based on data from “Use of Herbs Among Adults Based on Evidence-Based Indications: Findings From the National Health Survey,” by Bardia, et al., Mayo Clinic Proceedings, Vol. 82, No. 5). Use a 0.01 significance level to test the claim that fewer than 20% of adults consumed herbs within the past 12 months.
