Reducing Margin of Error with Simulation and Sample Size

The video tutorial explains how to assess parent satisfaction with school lunches using a survey and statistical methods. It covers the concept of confidence intervals, normal distribution, and how simulations can be used to estimate the margin of error. The tutorial emphasizes the importance of sample size in reducing the margin of error and narrowing the confidence interval, providing a more accurate estimate of the population parameter.

Describe the process of approximating the standard deviation using the range of data.

How can a simulation help in estimating the margin of error?

What does it mean if a confidence interval is too wide for the cafeteria manager?
