Question

Rosters Chicken advertises lite chicken with 30% fewer calories than standard chicken when the process for "The chicken breast production is n control the average chicken breast contains 410 calories, and the standard deviation in caloric content of the chicken breast population is 25 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. 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 (UC4,- calories (enter your response as an integer) Lower Control Limit (LCLİ)-O calories (enter your response as an integer hat are the imits ith three standard deviations from the targer? Upper Control Limit (UCLǐ,-D calories (enter your response as an integer) Lower Control Limit (LCLǐ)-D calories (enter your response as an integer)

Answer 1

Given that, Mean = m = 410

Standard Deviation = SD = 25

A) Z value = 4

Upper control limit = UCL = m + 4SD

= 410 + (4 x 25) = 510

Lower control limit = LCL = m - 4SD

= 410 - (4 x 25) = 310

B) Z value = 3

Upper control limit = UCL = m + 3SD

= 410 + (3 x 25) = 485

Lower control limit = LCL = m - 3SD

= 410 - (3 x 25) = 335
