Using two‐phase sampling mechanism, two alternative estimators in the presence of the available knowledge on second auxiliary variable z are considered, when the population mean of the main auxiliary variable × is unknown. The suggested estimators are found to be more eficient than the ratio‐type and regression‐type estimators suggested by KIREGYERA (1980, 1984).
