• Question 394:

  A set of data from a process has 8 readings per sample and 50 samples. The mean of the 50 sample means is 12.62. The mean of the 50 ranges is 0.18.Find control limits for the R chart.

  A. 0.10 and 0.25
  B. none and 0.33
  C. 0.02 and 0.33
  D. none of the above
  C. 0.02 and 0.33

  ---

  Explanation/Reference:

  The formula required to calculate control limits for the R chart are as follows:

  

  = 1.864 x 0.18 = 0.33

  

  

  = 0.1111 x 0.18 = 0.02

• Question 395:

  A set of data from a process has 8 readings per sample and 50 samples. The mean of the 50 sample means is 12.62. The mean of the 50 ranges is 0.18. Find the control limits for the xbar chart.

  A. 12.55 and 12.69
  B. 12.11 and 13.13
  C. 12.54 and 12.70
  D. none of the above
  A. 12.55 and 12.69

  ---

  Explanation/Reference:

  This formula is using control limit for the x bar chart

  

  = 12.62 + (0.373)(0.18) = 12.62 + 0.06714 = 12.69

  

  =12.62 ?(0.373)(0.18) =12.62 ?0.06714 = 12.55 UCL is 12.69 and LCL is 12.55
