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 430 ?calories, and the standard deviation in caloric content of the chicken breast population is 30 calories.
Rosters wants to design an x overbarx?-chart to monitor the caloric content of chicken? breasts, where 25 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?
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 the? target?
Does the standard deviation of the sampling distribution? change? Yes or No
The ?3-sigma x overbarx chart control limits? are:
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).
