For a given sample size, reducing the margin of error will mean higher confidence.
For a certain confidence level, you can get a smaller margin of error by selecting a larger sample.
For a fixed margin of error, smaller samples will mean lower confidence.
For a given confidence level, a sample 9 times as large will make a margin of error one ninth as big.
