Todd, I concur with stacase:
To restate what stacase said, AQL 1.5, Lot size N=51-90, Inspection Level II --->Sample size code letter "E". The up arrow indicates to use the row that the arrow points to, which is the "D" row. So you use n=8, Ac=0, the same as you used for your smaller lots of N=26-50.
So you do not have to change your sampling plan over the range N=26-90.
