We have 6 shipping containers containing 585 items / boxes each of the same item for a total of 3510 items / boxes. We strongly suspect a high rate of defective products but assume the high defect rate is limited to 1 or 2 batches (therefore only present in 1 or 2 containers).

If this assumption is correct, how many items / boxes do we need to open and inspect for each shipping container to give us 98% confidence that that container has an acceptable amount of defects (2% defect rate as opposed to 30% defect rate)?

Thanks for any and all help or referrals.
