A gauge repeatability and reproducibility study was made at Precision Parts, Inc., using three operators, taking three trials each on identical parts. The part specification for the collar that was measured was 12 1 inches.

a. Analyze the data.

b. Do you see any problems after analyzing the data? If so, what should be done?

Please give detailed answers for both questions.
