a) Standard deviation of the sampling means= 0.733 ounces (round your response to three decimal places). b) With z = 3, the control limits for the mean chart are: UCL; = 12.259 ounces (round your response to three decimal places). LCL; = = 7.861 ounces (round your response to three decimal places). c) The control limits for the R-chart are: UCLR = 8.672 ounces (round your response to three decimal places). LCLR = 0.000 ounces (round your response to three decimal places). d) Based on the x-chart, is one or more samples beyond the control limits? No Based on the R-chart, is one or more samples beyond the control limits? Yes
Refer to Table 56.1-Factors for Computing Control Chart Limits (3 sigma) for this problem. A process that is considered to be in control measures an ingredient in ounces. Below are the last 10 samples (each of size n = 5) taken. The population process standard deviation is 1.20.
