Automotive bolt diameter data

A manufacturing engineer assesses the automated attribute measurement system that is used for accepting or rejecting bolts. The engineer selects 10 parts that have known reference values and runs each part through a go/no-gage 20 times. The engineer records the number of acceptances for each part.

The system has a lower tolerance of −0.020 and an upper tolerance of 0.020.

You can use this data to demonstrate Attribute Gage Study (Analytic Method).
