Confidence intervals and football wins: During week 11 of the fall 2006 college football season, the population of 53 Division I-A games had a mean spread (winning score minus losing score) of 16.189, with a standard deviation of 12.128. We took a sample of four games that were played that week in the next-highest division, Division I-AA, to see if the spreads were different; one of the many leagues within Division I-AA, the Patriot League, played four games that weekend. Their mean was 8.75. In statistics, why don't we talk about having 100% confidence?

Error is always expected

Explanation:
