Refer to Table 56.1 - Factors for Computing

Refer to Table 56.1 - Factors for Computing Control Chart Limits (3 sigma) for this problern. 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 5 5 6 Sample Mean (in.) 13.804 13.800 13.791 13.808 13.797 13.799 Range (in.) ) 0.033 0.041 0.034 0.051 0.031 0.036 Sample Sample Mean (in.)

Based on the sampling done, the controllimits for 3-sigma chart are: Upper Control Limit (UCLX) - inches (round your response to four decimal places). Lower Control Limit (LCL) -Inches (round your response to four decimal places). Based on the chart, is one or more samples beyond the control limits? For the given data, the R- inches (round your response to four decimal places). The contrul limits for the 3-sigma R-chart aru: Upper Control Limit (UCLA) - inches (round your response to four decimal places). Lower Control Limit (LCLR) = inches (round your response to four decimal places). Enter your answer in each of the answer boxes. 7
