The union decides to sample 402 of its members at random and monitor the working time of each of them for 1 month. At the end of the month, the total number of hours absent from w ...

A random sample of students gave a sample average of $3975, and a 95% confidence interval was found to be $3525 < µ < $4425. This interval is interpreted to mean that (1) if the study were to be repe ...

So I cannot analytically demonstrate why the Gaussian is immediately a good approximation to μ while it takes higher n for it to be a good approximation to x, but it must be due to the asymm ...

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.
