“…The first attempt was made by Cochran [1] to investigate the problem of estimation of the population mean when auxiliary variables are present and he proposed the usual ratio estimator of population mean. Other authors like, Hartley-Ross [2], Quenouille's [3], Singh [4,5], Abu-Dayeh et al [6], Kadilar and Cingi [7], Khoshnevisan et al [8], Perri [9], Singh et al [10], Singh et al [11], Singh and Kumar [12], Tailor et al [13], Lu [14], Sharma and Singh [15], Lu and Yan [16], Verma et al [17], Audu and Singh [18], Hafeez and Shabbir [19], Audu et al [20,21], Audu et al [18,[22][23][24][25][26], Audu and Adewara [27], Ahmed et al [28][29][30][31], Hafeez et al [32], Yunusa et al [33], Zaman et al [34], Hafeez et al [35], Ahmed and Singh [36], Neyman [37], Singh et al [38] have also considered the problem of estimating the mean and other parameters of study variables when auxiliary variables are made available. There are many practical situations when auxiliary information is qualitative in nature, i.e, auxiliary information is available in the form of an attribute, such as the height of a person may depend on the fact that whether the person is male or female, the efficiency of a dog may depend on the particular breed of that dog, or the yield of whea...…”
