Question: Refer to Table 56.1. Factors for Computing Control Chart Line (3.alama) for this problem Twelve samples, each containing five parts, were taken from a process

Refer to Table 56.1. Factors for Computing Control Chart Line (3.alama) for this problem Twelve samples, each containing five parts, were taken from a process that produces steel rods at Emmanuel Kodzi's factory, The length of each rod in the samples was in The results were tabulated and sample means and ranges were computed. The results were: Sample Sample Mean Sample Mean Range (in.) Sample (in.) (in.) Range (in.) 1 8.600 0.033 7 8.603 0.041 2 8.600 0.041 & 8.600 0.034 3 8.591 0.034 9 8.595 0.027 4 8.606 0.051 10 8.601 0.029 5 8.597 0.031 11 8.601 0.039 6 8.597 0.036 12 8.606 0 047 For the given data, the = 8.6000 inches (round your response to four decimal places) Based on the sampling done, the controllimits for 3-sigma x chart are: Upper Control Limit (UCL;) - inches (round your response to four decimal places)
