# Question: Ten parts are measured three times by the same operator

Ten parts are measured three times by the same operator in a gauge capability study. The data are shown in Table 8E.9

(a) Describe the measurement error that results from the use of this gauge.

(b) Estimate the total variability and product variability.

(c) What percentage of total variability is due to the gauge?

(d) If specifications on the part are at 100 ± 15, find the P/T ratio for this gauge. Comment on the adequacy of the gauge.
