Chapter 8, Problem 38
| Incorrect. | |
Samples of size n=6 are collected from a process every hour.
After 20 samples have been collected, we construct the control
chart with σ=1.40, UCL = 21 and LCL=18. Suppose that the
mean shifts to 18.5. (a) What is the probability
that this shift will be detected on the next sample? Round your
answer to four decimal places (e.g. 98.7654). (b)
What is the ARL after the shift? Round your answer to three decimal
places (e.g. 98.765).
