Tables to Facilitate Calculation of an Asymptotically Optimal t Test for Equality of Location Parameters of a Certain Extreme-Value Distribution

A t test, proposed by Ogawa and based on the use of a few sample quantiles selected from large samples, is considered for testing the hypothesis H
₀
: μ
₁
= μ
₂
against the hypothesis H
₁
: μ
₁
≠ μ
₂
concerning the location parameters μ
₁
and μ
₂
of two extreme-value distributions with common unknown scale parameter σ. Tables that simplify the calculation of the test statistic and an example illustrating their use are provided.
