Rosters Chicken advertises "lite" chicken with 30% fewer calories than standard
chicken. When the process for "lite" chicken breast production is in control, the average
chicken breast contains 460460 calories, and the standard deviation in caloric content
of the chicken breast population is 2525 calories.
Rosters wants to design an x overbarx-chart to monitor the caloric content of chicken
breasts, where 2525 chicken breasts would be chosen at random to form each sample.
a) What are the lower and upper control limits for this chart if these limits are chosen to
be four standard deviations from the target?
b) What are the limits with three standard deviations from the target? - Answers - A)
UCL = 480
LCL = 440
B) UCL = 475
LCL = 445

D.
eliminate natural variations - Answers - B
Process capability
A.
exists when CPK is less than 1.0.
B.

means that the natural variation of the process must be small enough to produce
products that meet the standard.
Your answer is correct.

C.
some times leads demand, and at other times lags.
D.
works best when demand is not growing but is stable.
