Refer to your textbook Table 56.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. Twelve samples, each containing five parts, were taken from a process that produces steel rods at 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 Mean (in.) Range (in.) 1 8.602 0.033 12 8.604 0.041 3 8.593 0.034 4 8.606 0.051 5 8.597 0.031 6 8.601 0.036 17 8.601 0.041 8 8.605 0.034 9 8.595 0.027 10 8.603 0.029 11 8.601 0.039 12 8.608 0.047 Use the given data to determine the 3-sigma UCL, LCL, and the overall means for x-bar charts and R-charts. x-double bar = 8.60 inches (round your response to two decimal places). UCL (x-bar) - [Select ] inches (round your response to two decimal places). LCL (x-bar) - [Select] inches (round your response to two decimal places). Based on the x-bar chart, is one or more samples beyond the control limits? (Select] R-bar Select] inches (round your response to two decimal places). UCL (R) = [Select ] inches (round your response to two decimal places). LCL (R) = [Select] inches (round your response to two decimal places). Based on the R-chart, is one or more samples beyond the control limits? (Select]
