[EX08-079] You are a quality-control inspector and are in a position to make the decision as to whether a large shipment of cork stoppers for use in bottling still (versus bubbly) wine passes inspection.

Once you inspect the mandatory number in the approved manner you will make a decision to accept or reject the lot.

Part 1 of the inspection requires you to randomly select 32 corks and measure three physical dimensions of the cylindrical stopper according to defined procedures.

Specification Limits Diameter 24 mm 0.5 mm Ovalization 0.7 mm Length 45 mm 0.7 mm Acceptance Quality Levels (AQL)

The batch is accepted if no more than two corks present an inferior or superior result to the limits of specification.

The batch may be refused if three corks or more present an inferior or superior result to the limits of specification.

(All measurements are in millimeters.)

a. Determine the number of corks that pass part 1 of the inspection.

b. State the decision and explain how it was reached.

c. Prepare a short written report summarizing the requirements and your findings and decision.
