Аннотация:This article provides the analysis of the statistical properties
of a random grain quality assessment for the best case. In
addition, the distribution of the true unknown grain quality
value is derived under the condition of a fixed sample and its
main characteristics. The work is designed to select a sample
size that can theoretically provide the required quality of the
assessment, as well as to set algorithms for assessing grain
quality and comparing their experimentally measured quality
of work with theoretically the maximum achievable
performance.
