S6.11: 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 determined. The results were tabulated and sample means and ranges were computed. The results were: 1. Determine the upper and lower control limits and the overall means for. Xbar charts and R-charts. 2. Draw the charts and plot the values of the sample means and ranges. 3. Do the data indicate a process that is in control? 4. Why or why not? S7.1. Amy Xia's plant was designed to produce 7,000 hammers per day but is limited to making 6,000 hammers per day because of the time needed to change equipment between styles of hammers. What is the utilization? S7.2.
