http://gchang.people.ysu.edu/class/mph/note/06_5_CI_OneSidedCI.pdf Weblower confidence levels result in smaller intervals: 90% CI's are smaller than 95% CI's and these are smaller than 99% CI's. The tradeoff here is that smaller intervals are less likely to contain the parameter we're after: 90% versus 95% or 99%. More precision, less confidence and reversely. larger sample sizes result in smaller CI's. cable providers in okc https://joshtirey.com
