Assume two independent populations are given. The associated independent random
vari-ables have Normal distributions with unknown expectations

1. Introduction
Assume two populations 11"1 and 11"2 are given. The related independent random variables,
which may be sample means, are denoted byXl and X2 , respectively. The random variable
Xi (i
=
1,2) has a Normal distribution with unknown expectation ()i and known variance (72.Without loss of generality we can assume (72 = 1. The ordered expectations are denoted by
8[1] ~ 8[2]' The best population is defined as the population with parameter()(2]. We assume there is not a tie. The subset selection procedure selects a subset, non-empty and as small as possible, with the probability requirement that the probability of a correct selection is at
least P*

subset if and only ifXi

natural loss function has been considered. Indicating the subset size by S, in Van der Laan
