<dc:description xml:lang="es">Sumario: In industrial environments it is common for pollutant concentrations to be approximately lognormal. Unfortunately, when based on small samples from lognormal distributions, the ordinary student's t-statistic has some undesirable characteristics which are not recognized widely by practicing industrial hygienists. In this paper, the authors demonstrate the difficulties in using the ordinary student's t-statistic to evaluate the average exposure, explore the properties of alternative test statistics, and make some general observations on the implications of these findings</dc:description>
