... Random samples of 10 packs are taken regularly from the production line and the mean weight of the sample is found. Use the CLT to find the approximate proportion of samples that should have a mean weight > 253g. The distribution of the population is not known but it is implied that n is big enough ...

... Using Point Estimates We know that the mean score on an intelligence test in the general population is 100 with a standard deviation of 15. The mean based on a sample of size 100 from a program for accelerated students is 108. Clearly, there is a difference between the population and sample means. W ...

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.
