. Consider a single-sampling plan with it =

25, c = 0. Draw the OC curve for this plan. Now consider chainsampling 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 simadon compared to the conventional single-sampling plan with c = 0.
