 Refer to Table $6.1 - Factors for Computing Control Chart Limits

Refer to Table $6.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. Twelve samples, each containing five parts, were taken from a process that produces steel rods at Emmanual Kodzi's factory. The length of each rod in the samples was determined. The results were tabula sample means and ranges were computed. The results were: Sample Sample Sample Mean (in.) Range (in.) Sample Mean (in.) Range (in.) 8.204 0.044 8.201 0.021 8.204 0.051 8.207 0.058 8. 189 0.042 8. 197 0.039 NOOPEN 8.204 0.037 8.201 0.038 8. 195 0.048 8.203 0.054 8. 197 0.053 8.204 0.061 For the given data, the x = inches (round your response to four decimal places). X Definition Based on the sampling done, the control limits for 3-sigma x chart are: Upper Control Limit (UCL-) = inches (round your response to four decimal places). Sample Mean Factor, Upper Range, Lower Range, Size, n Lower Control Limit (LCL-) = |inches (round your response to four decimal places). 1.880 3.268 1.023 2.574 Based on the x-chart, is one or more samples beyond the control limits? 0 729 2.282 0.577 2.115 For the given data, the R = inches (round your response to four decimal places). 0.483 2.004 O 0.419 1.924 0.076 The control limits for the 3-sigma R-chart are: 0.373 1.864 0. 136 0.337 1816 0. 184 Upper Control Limit (UCL) = inches (round your response to four decimal places). 0.308 1.777 0.223 0.266 1.716 0 284 Lower Control Limit (LCL) = inches (round your response to four decimal places).
