a. Calculate the probability of lot acceptance, P(A), for p = .10, .02, …, .05, and sketch the OC curve.
b. Sketch the OC curve in problem 85 above (with n = 50, and c = 1) and the OC curve in part (a) of problem 86 (with n = 100, and c = 2) on the same set of axes. Which of the two plans is preferable (leaving aside the cost of sampling) and why?
