[1] using product of sample size and conventional location parameters. The results obtained on the Mean Square Errors using the same data set used by Abid et al. shows that the newly modified ratio-type estimators perform better vis-à-vis the Abid et al. estimators, hence, recommended for usage in Sampling.enPopulation, Estimator, Sample size, Parameter, EfficiencyArticle
