Refer to Table S6.1-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 and sample means and ranges were computed. The results were: Sample 1 23456 Sample Mean (in.) 12.404 12.400 12.393 12.406 12.399 12.399 = For the given data, the x = 12.4012 inches (round your response to four decimal places). 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). = [ Range (in.) Sample Sample Mean (in.)
