Question: Suppose that a clinical trial is conducted to test how effectively Prilosec OTC prevents nighttime heartburn in frequent heartburn sufferers. In a study of 100 people who experience heartburn 2 or more days a week, it was found that 82% of these individuals did not experience heartburn at night while using Prilosec OTC. Use MegaStat to create a 95% confidence interval on the proportion of frequent heartburn sufferers who do not have heartburn at night while using Prilosec OTC. What is the conceptual difference between the point estimate of 82% and your confidence interval?
