Consider for a process in control, the value of alpha is .0015. What is the value of the average run length?
-
666 ( 1/alpha gives us an estimate of average run length)
-
555
-
444
-
Consider that for a particular process, the p has shifted to .4 and the process has gone out of control. The corresponding value of beta is found to be .3356. The value of Average Run Length is:
-
2.5
-
1.5 ((1/1-beta) provides us with average run length)
-
1.0
