Small variance implies that our estimates will be precise with large probability. Let X be the sample mean based on a random sample of size n from a dis ...

If V lies between 99 and 95% or between 5 and 1%, the numbers are suspect, between 90 and 95% or between 5 and 10% the numbers might be "almost suspect".

German tank problem
In the statistical theory of estimation, the problem of estimating the maximum of a discrete uniform distribution from sampling without replacement is known in English as the German tank problem, due to its application in World War II to the estimation of the number of German tanks.The analyses illustrate the difference between frequentist inference and Bayesian inference.Estimating the population maximum based on a single sample yields divergent results, while the estimation based on multiple samples is an instructive practical estimation question whose answer is simple but not obvious.
