| Abstract: | In the present paper, a new problem in survey sampling has been considered and an attempt has bcen made to find its solution. The procedures available in literature deal with the estimation of mean of a sensitive quantitative variable for the whole population. Sometimes the investigator may be interested in estimating the mean of a sensitive quantitative variable for a sub-group of the population. At the same time, he/she may also be interested in estimating the size of this sub-group. In this paper, we have obtained estimators of these parameters. Approximate bias and variance expressions are also obtained for these estimators. |
