Reducing Margin of Error with Simulation and Sample Size

This video explains how to use simulation to decrease the size of a confidence interval, using the example of a cafeteria manager who wants to know how many parents of school children believe that school lunches are satisfactory. The video covers the concepts of normal distribution, margin of error, sampling distribution, and confidence interval, and shows how increasing the sample size can reduce the margin of error and provide a narrower range of likely values for the population proportion.
