A random sampling technique was use in selection of 50 respondents. The data obtained was analyzed using descriptive statistics and gross margin analysis. It was realized that, majority (36%)of the respondents who engaged in cowpea  processing into cowpea fried paste are within the age bracket of 40-49 years and also of female folk (100%).The women who engaged in this business (88%) had about 1-9 as household size.(48%)of the respondents had informal education.

DESIGNING OF GENERALIZED TWO-PLAN SYSTEM WITH REFERENCE SAMPLING PLAN (Published)

This paper proposes a generalized two-plan sampling system with multiple repetitive group sampling plan as the reference plan, designated as GTPMRGSS (n; cN, cT), is introduced. The efficiency of GTPMRGSS (n; cN, cT) with respect to smaller sample sizes have been established over the attributes scheme. The sampling inspection scheme will be useful when testing is costly and destructive. The advantages of the sampling inspection scheme over attributes single, double and various reference plans are discussed. Tables are constructed considering various combinations of acceptable and limiting quality levels and with their operating ratios.
