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 400 calories, and the standard deviation in caloric content of the chicken breast population is 30 calories. Rosters wants to design an x overbar-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 overbar)equals nothing calories (enter your response as an integer).
Square both sides x+10=x^2-4x+4 subtract x from both sides 10=x^2-5x+4 subtract 10 from both sides 0=x^2-3x-6 factor what 2 numbers multiply to get -6 and add to get -5 the numbers are -6 and 1 so (x-6)(x+1)=0 if xy=0 then assume x and y=0 so x-6=0 x=6 x+1=0 x=-1
