. In a study to isolate both gauge repeat-

ability and gauge reproducibility, two operators use the same gauge to measure 10 parts three times each. The data are shown here.

(a) Estimate gauge repeatability and reproducibility,

(b) Estimate the standard deviation of measurement error.

(c) If the specifications are at 50 + 10.
what can you say about gauge cape-
bility?
