A member of the Lottery Commission requests a 90% confidence interval estimate but with a smaller margin of error. How can we get a smaller margin of error using 90% confidence? A) Take a smaller sample because smaller samples result in smaller margins of error.      B) Take a larger sample because larger samples result in smaller margins of error.      C) Take another sample of the same size because you might get lucky and get a smaller margin of error.      D) Take a sample of the same size from the adults in Ohio instead of the entire country. Then the population will be smaller and this will give a smaller margin of error.
