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.
Correct Answer:A
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
