Here is the example that I use that may be more familiar:

School Bond for constructing a new building

Pre-Election pollinghas the voters approving at 52%

WITH a MARGIN OF ERROR (E) of 4%

Should the school district start digging?? no-----Why????

Confidence Interval--Given the Sample Data and Margin of Error, where might the results land???

(52 - 4, 52 + 4) = (48, 56)-----at 48%, the bond does not pass. At 56%, it passes easily.

(x -E, x + E) x = sample mean E = Margin of Error

Confidence Level, which has to do with precision, will affect the size or width of the Confidence Interval.

Find an example of a confidence interval in the news, scholarly source, or medical journal like the one mentioned above. Summarize the article/study. Does the article/study include the sample size and the level of confidence used to create the confidence interval? Explain what the confidence interval means in the context of the news article or scholarly source.
