9. Tolerances for a bicycle derailleur are 6 cm +/− .001 cm. The current process produces derailleurs with

a mean of 6.0001 with a population standard deviation of .0004. The process population is normally

distributed.

a. Is the process capable?

b. If not, what proportion will meet specs?

c. Within what values will 75% of sample means of this process fall if the sample size is 6 and the

process is stable?
