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 Sample Sample Mean Range (in.) 1 2 3 4 5 6 Sample Mean (in.) 8.602 8.604 8.591 8.604 8.597 8.597 (in.) 0.033 0.041 0.034 0.051 0.031 0.036 7 8 9 10 11 12 (in.) 8.601 8.607 8.597 8.603 8.603 8.606 0.041 0.034 0.027 0.029 0.039 0.047 For the given data, the x = inches (round your response to four decimal places).
