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.

1.

The simulated sampling distribution of p^\hat{p} for a survey has a standard deviation of about
0.050.05. The margin of error is about two standard deviations. What is the margin of error?
