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 Kodzi'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 Range (in.) 1 2 3 0.041 Sample Mean Range Sample Sample Mean (in.) (in.)

Based on the sampling done, the control limits for 3-sigma x chart are: Upper Control Limit (UCL-) = 13.723 inches (round your response to four decimal places). Definition Lower Control Limit (LCL;) = 13.6804 inches (round your response to four decimal places). Lower Range, D. Based on the x-chart, is one or more samples beyond the control limits?
