QUESTIONS A quality analyst wants to construct a control chart for determining whether three machines, all producing the same product. are under control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine with the following results: Machine Measurements # 1 17 15 15 17 #2 16 25 18 25 #3 23 24 23 22 What is the estimate of the process mean for whenever it is under control O 16 OOOOO 19 20 21 23 QUESTION 10 A quality analyst wants to construct a control chart for determining whether three machines, all producing the same product, are under control with regard to a particular quality variable.
