Below is a link to a file with several real-world data sets. Choose one of the variables (a column of data) and construct a confidence interval. You can do this either by hand or by software. Either way, report your confidence interval in your initial post and then do the following: 1. Give an introduction to your variable (what do your numbers represent?). 2. What does the confidence interval say about the variable? Is there a large or small amount of spread?
