Assuming that you have attribute data and that you want to be 95% confident of rejecting a lot if it is 1% defective or more:

n=295, Ac=0

n=471, Ac=1

n=626, Ac=2

n=772, Ac=3

For the plans with Ac greater than zero, the sample sizes will be less if tou use sequential decision rules. You can calculate these decision rules and much more with software program TP105. See:
