Abstract In life‐testing situations under bivariate normality of ( X, U ), a few smallest or a few largest Y ‐observations may not be available. Tests for μ = 0 (mean vector) and o = 0 (correlation coefficient) are developed from the available Y ‐observations and their concomitant X ‐observations. The robustness of these tests to departures from normality is investigated.
