Attribute Control Charting


  1. Special plastics make blanks for credit cards. They use a P chart to keep track of the Number of non-conforming cards that are created when a batch of blank cards is run. A study was conducted for 7 days, with samples of 100 cards taking each day. The nonconformances (np) are tabulated for each day as follows:


DAY NP (non-conformances) PValues
1 17  
2 14  
3 21  
4 16  
5 44  
6 12  
7 19  



NOTE: Place your answers in the essay field I love this question field and identifying them clearly. If possible show your calculations. State the values clearly, such as: Process mean Pbar= x.xx


  1. Calculate the process mean as a decimal (p bar)
  2. Calculate the upper control limit (UCL)
  3. Calculate the lower control limit (LCL)
  4. Is there any sign of variation to two special issues? Explain your reasoning.




  1. Construct X Manufacturing makes metal rods of specified lengths for construction contractors. One customer has specified lengths of 39 to 49 cm. Construct X has conducted an analysis that indicates shafts that average 42.9 cm in length, with a standard deviation of 0.75 centimeters.


  1. Calculate the Cp value to determine if construct X’s production system is capable of meeting its customers’ requirements. Hint: there is no need to use the D to constant. Just assume that sigma is the same value as sigma estimated.


Cp value=
