a) What are the lower and upper control limits for this chart if these limits are chosen to be four standard deviations from thetarget?
Upper Control Limit (UCL - subscript x) = _______ calories(enter your response as an integer).
Lower Control Limit (LCL- subscript x) = ________calories(enter your response as an integer).
b) What are the limits with three standard deviations from thetarget?
The 3-sigma x overbarx chart control limitsare:
Upper Control Limit (UCL - subscript x) =___________ calories(enter your response as an integer).
Lower Control Limit (LCL - subscript x) = _______ calories(enter your response as an integer).
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 450 calories, and the standard deviation in caloric content of the chicken breast population is 30 calories. Rosters wants to design an X-chart to monitor the caloric content of chicken breasts, where 25 chicken breasts would be chosen at random to form each sample.
