Question
The general model for a Shewhart control chart is given as:
UCL = µw + Za/2
LCL
Hw - Za/2
If the value of Za/2
2.81, the value of ARLO is:
Suppose that there is a mean shift of one standard deviation in the process mean. Considering
n = 4 and Za12 = 2.81, what is the value of ARL1
[Provide your answer
with two decimal places]
