Herb Consumption

Among 30,617 randomly selected adults, 5787 consumed herbs within the last 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 .05 significance level to test the claim that fewer than 25% of adults consumed herbs within the last few months. Identify the critical value(s), given a significance level and illustrate the region(s) of rejection(do all calculation by using minitab)
