A process that produces explosion-proof fittings has an output that is normally distributed with a mean of 6 cm.and a standard deviation of .01 cm.A job is to be run that requires 200 fittings.
(i)Determine three sigma control limits for an x-bar chart assuming a sample size of 10.
(ii)If specifications are 5.98 to 6.02,what run size should be used for this job so that the expected number of good pieces is 200,assuming the process is in control?
