Question: Problem 6s.11ac Refer to Table 56.1 - Factors for Computing Control Chart Limits (3.sigma) for this problem Twelve samples, each containing five parts, were taken

Problem 6s.11ac Refer to Table 56.1 - 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 Kodi's factory. The length of each rod in the samples was determined. The results were tabulated and sample means and ranges were computed. The results were: Sample Sample Mean (in.) 14.602 14 602 14.589 14.606 14.595 14.599 Range (in.) 0.044 0.051 0.042 0.037 0.048 0.053 Sample Sample Mean (in.) Range (in.) 14.601 0.021 14.607 0.058 14.595 0.039 14.601 0.038 14.601 0.054 14.606 0.061 For the given data, the x- inches (round your response to four decimal places). Sample Size, n Upper Range, Lower Range, D4 ches Mean Factor, A2 1.880 1.023 0.729 0.577 0.483 0.419 0.373 0.337 0.308 0.266 3.268 2.574 2.282 2.115 2.004 1.924 1.864 1.816 1.777 1.716 0.076 0.136 0.184 0.223 0.284 Print Done wer box and then click Check Answer For the given data, the x double overbar = __ inches (round your response to four decimal places) Based on the sampling done, the control limits for 3-sigma x overbar chart are: Upper Control Limit (UCL Subscript x overbar) = - inches (round your response to four decimal places). Lower Control Limit (LCL Subscript x overbar) = inches (round your response to four decimal places). Based on the x overbar-chart, is one or more samples beyond the control limits? YES or NO? For the given data, the Upper Roverbar = _ (round your response to four decimal places). The control limits for the 3-sigma R-chart are: Upper Control Limit (UCL Subscript Upper R) = Linches (round your response to four decimal places) Lower Control Limit (LCL Subscript Upper R) = inches (round your response to four decimal places) Based on the R-chart, is one or more samples beyond the control limits? Yes or No
