A normally distributed process has specifications of LSL = 50 and USL = 60 on the output. A random sample of 25 parts indicates that sample mean = 56 and sample standard deviation = 2. Assume that the target value is centered between specification limits (target=55). Obtain the estimate of Cpm. Is this process capable? (Note that if Cpk ≥ 1.0, a process is capable)
