Refer to Table $6.1 - Factors for Computing

Refer to Table $6.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. A process that is considered to be in control measures an ingredient in ounces. Below are the last 10 samples (each of size n = 5) taken. The population process standard deviation is 1.36. 1 4 7 8 9 9 10 10 8 9 8 12 2 10 10 12 12 9 3 14 10 9 10 10 11 Samples 5 6 13 9 10 11 9 9 12 12 11 8 7 7 10 10 10 8 14 16 8 10 13 9 8 12 11 9 12 13 9 9 10 7 9 10 a) Standard deviation of the sampling means = .608 ounces (round your response to three decimal places) b) With z = 3, the control limits for the mean chart are: UCL- = 12.005 ounces (round your response to three decimal places). LCL; = 8.355 ounces (round your response to three decimal places). x c) The control limits for the R-chart are: UCLR = ounces (round your response to three decimal places)
