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 1 2 3 4 Sample Mean (in.) 12.600 12.602 12.593 12.608 12.595 12.597 Range (in.) Sample Sample Mean (in.)
