摘要: In this paper we consider the problem of estimating expected value a fuzzy-valued random element in samplings from finite populations. To purpose, quantify associated sampling error by means parameterized measure have introduced previous paper. Keywords: Aumann's integral, fuzzy variable, variable, $$\bar \lambda $$ -mean squared dispersion, samplings, set.
