In a study to isolate both gauge repeatability and gauge reproducibility, two operators use the same gauge to measure ten parts three times each. The data are shown in Table 8E.10.

(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 capability?
