| Abstract: | This paper presents an alternative derivation of the expected value and variance of the sample lead to the one given in a previous paper. It deals with the case of random sampling from infinite population without replacement or from finite population with replacement. The derivation involves the use of the moment- and cumulant-generating functions, but is shorter and simpler than the original proofs. |
