Given are k(≧2) exponential populations differing only in their location parameter. One wishes to choose the best one, that is the population with the largest value of the location parameter. A possible method for solving this problem is to select a subset of the k populations of size at least one which includes the best population with a required confidence P *(k −1 ≤ P * ≤1). In this paper the required selection constant is determined for different values of k and P *. Also an approximation for the selection constant is derived. A comparison with the exact results is made.
