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?
