In this paper, we introduce a new sampling plan based on the defective proportion of batch. The proposed sampling plan is based on the distribution function of the proportion defective. A continuous loss function is used to quantify deviations between the proportion defective and its acceptance quality level (AQL).  For practical purpose, a sensitivity analysis is carried out on the different values of the required sample sizes that allow practitioners to design near optimal inspection plans. A numerical example is presented to illustrate how the proposed procedure can be applied to design acceptance plans.
