It says NOTHING about "where you'll find 95% of the data." You're not confident in the data, you're confident in the result of the experiment lying within a certain range (the confidence interval) 19 times out of 20.Darren Kuropatwahttps://www.blogger.com/profile/08462283847470560887noreply@blogger.com
