Refer to Table 56.1Factor for Computing Control Chart Limits3.a) for this problem Twelve samples, each containing five parts, were taken from a process that produces stoel rods at Emmanuel Koda'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 fin.)
