Question: A Find the appropriate Dodge Romig plan b Find the ATI for
a. Find the appropriate Dodge-Romig plan.
b. Find the ATI for this plan, assuming that incoming lots are 1% defective.
c. Suppose that our estimate of the supplier’s process average is incorrect and that it is really 0.25% defective. What sampling plan should we have used? What reduction in ATI would have been realized if we had used the correct plan?
