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 Sample Sample Mean (in.) Range (in.) 7 1 2 8 Sample Mean (in.) 13.204 13.200 13.191 13.206 13.195 13.201 Range (in.) 0.033 0.041 0.034 0.051 0.031 0.036 3 9 13.201 13.207 13.195 13.203 13.203 13.204 0.041 0.034 0.027 0.029 0.039 0.047 4 10 5 11 12 6 For the given data, the x = inches (round your response to four decimal places). Jamison Kovach Supply Company manufactures paper clips and other office products. Although inexpensive, paper clips have provided the firm with a high margin of profitability. Sample size is 40.
