# Question

Consider a single-sampling plan with n = 25, c = 0. Draw the OC curve for this plan. Now consider chain-sampling plans with n = 25, c = 0, and i = 1, 2, 5, 7. Sketch the OC curves for these chain-sampling plans on the same axis. Discuss the behavior of chain sampling in this situation compared to the conventional single-sampling plan with c = 0.
