You are conducting research for a popular blog to find out the proportion of readers who are satisfied with the site's newly designed navigation. You want to make sure that you increase your chances for capturing the true proportion of readers who are satisfied, but the margin of error is too large.

Which of the following would you do?

A. Use a larger confidence level, but choose a smaller margin of error

B. To increase your confidence, you must be willing to accept a smaller margin of error

C. To get a smaller margin of error, you must be willing to accept lower confidence

D. All of the above

Answer: Option (C) is correct option

Explanation:

Margin of error is the factor that occurs in survey for determining random sampling error. It indicates about confidence interval (CI) through describing difference occurring in poll result and actual population value. If there is high margin of error, then confidence is low because poll result will not reflect the actual population result collected through survey.

According to the question, researcher would try to get small margin of error so that lower confidence interval can be acceptable because large confidence interval (CI) will indicate more margin of error.

Other options are incorrect because small margin of error cannot produce increment in confidence or usage of large confidence. Large confidence interval will result in large margin of error. Thus, the correct option is option (c).
