In a gauge R&R study, 2 inspectors use the same gauge to measure 10 different batches of parts 3 times each. For each inspector, the averages and ranges of the 3 measurements on each batch are given below (units are in mm) Batch Inspector 1 Inspector 2 Number 149/3 149/3 155/3 153/3 mom . 153/3 157/3 150/3 149/3 145/3 145/3 152/3 152/3 153/3 151/3 in m N 151/3 151/3 151/3 148/3 142/3 141/3 Average 150.1/3 149.6/3 (a) Please estimate Ogauge- (8 points) (b) Suppose the total observed variance (O-total) is 5.60mm. Estimate the variability of product. (6 points) (c) Suppose the USL and LSL are 50 + 10mm, respectively. Assess the capability of the measurement system (6 points)
