"The average lifespan of a fruit fly is between 1 day and 10 years" is an example of a confidence interval, but it's not a very useful one. From scientific measures to election predictions, confidence intervals give us a range of plausible values for some unknown value based on results from a sample. Let's learn to make useful and reliable confidence intervals for means and proportions.
