Question:

12.3. A pin shows good control on OD ¼ outside diameter with y-double bar¼0.21440, R-bar¼0.00032 in. for samples of n¼5. A mating collar also shows good control on ID, with x-double bar¼0.21503, R-bar¼0.00040 in. and n¼5.

Estimate the process standard deviations for each. Let the diametral clearance be w¼xy, and estimate mw and sw.

Assuming normal distributions, what percentage of pairs of pin and collar will have clearance less than 0.0001 in.?
