A measurement systems experiment involving 20 parts, three operators, and two measurements per part is shown in Table 8E.12.

(a) Estimate the repeatability and reproducibility of the gauge
(b) What is the estimate of total gauge variability?
(c) If the product specifications are at LSL = 6 and USL = 60, what can you say about gauge capability?
