QUESTION 2 (a) What steps can be taken to develop

QUESTION 2 (a) What steps can be taken to develop benchmarks? Why does benchmarking fail? (4 marks) 6) How Taguchi's quality strategy differs from conventional quality control strategy? (3 marks) c) A process that is considered to be in control measures an ingredient in kilograms. Some sample data from the process was collected as presented in the following table. The population standard deviation is 1.36. Samples 2 3 3 5 6 7 8 10 Weight (Kg) 10 9 10 9 12 9 9 11 11 10 13 9 10 10 9 10 10 11 10 10 12 10 9 11 10 10 10 8 12 9 10 11 10 8 9 13 10 8 10 8 8 8 12 12 9 10 12 9 8 12 Determine: 1) What is the standard deviation of the sample mean? (11) Develop two appropriate control charts for this process considering 36 limit. (11) In real life applications, if you find some observations are outside the control limits, what would be your course of action? (5+9+4=18 marks)
