  C. 2.7 and 7.5

  D. none of the above

  Correct Answer: D

• Question 422:

  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.A customer requires that SPC charts be done on their forms which have spaces for only 5 readings per sample. In preparation for calculating the new control limits the following question is asked, "Will the new average range be larger or smaller than the current average range?". The answer is:

  A. yes

  B. no

  C. maybe

  D. smaller

  E. larger

  F. same size

  G. none of the above

  Correct Answer: D

• Question 423:

  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.A customer requires that SPC charts be done on their forms which have spaces for only 5 readings per sample. What should be the UCL and LCL for tbe new averages chart?

  A. 12.53 and 12.71

  B. 12.58 and 12.66

  C. 11.61 and 13.63

  D. none of the above

  Correct Answer: A

• Question 424:

  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 a median chart.

  A. 12.52 and 12.72

  B. 12.54 and 12.70

  C. 0.02 and 0.33

  D. none of the above

  Correct Answer: A

• Question 425:

  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

  Correct Answer: C

  Explanation: 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 426:

  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

  Correct Answer: A

  Explanation: 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
