Exercises: Estimate a Population Mean or Proportion with a Margin of Error
Work through each section in order. Show your work where indicated. When you report an estimate, give the point estimate, the margin of error (about two standard deviations of the simulated sampling distribution), and the interval estimate, and interpret it in context.
