Which of the following would produce a confidence interval with a larger margin of error than

the 90% confidence interval? Clearly circle only one response.

A. Sampling only 5 households instead of 10, because 5 are easier to manage.

B. Sampling 5 households rather than 10, because a smaller sample size will result in a larger

margin of error.

C. Sampling 20 households rather than 10, because a larger sample size will result in a larger

margin of error.

D. Computing an 85% confidence interval rather than a 90% confidence interval, because a

larger confidence interval will result in a larger margin of error.
