... of -1.75 and 138 bushels corresponds to z = 1.75. From the z-table, the area under the z-curve between these two values = 0.9198. 1.b. Find the z-value with .0500 area to its left in the z-table to be -1.645. Similarly, the z-value with .9500 area to its left is found in the z-table to be 1.645. Usi ...

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.
