1. Develop 3 sigma level process control charts for monitoring weight of boxes that contain apples. You performed samplings over 5 weeks with sample size of 4 (n = 4). Draw variable control charts (mean and range). Calculate and show values for UCL, CL, and LCL using the factors provided in below table. Discuss your graphs and make your conclusion.
