A process is in control with x = 100.s = 1.05, and n = 5. The process specifications are at 95 ±
10. The quality characteristic has a normal distribution.

(a) Estimate the potential capability.
(b) Estimate the actual capability.
(c) How much could the fallout in the process be reduced if the process were corrected to operate at the nominal specification?

i-x = 100; s= 1.053, =s/G = 1.05/0.9400 = 1.117
