8. (-17 Points) DETAILS ASWSBE14 21.E.005. MY NOTES ASK YOUR TEACHER Temperature is used to measure the output of a production process. When the process is in control, the mean of the process is - 120.5 and the standard deviation is a -0.4. (a) Compute the upper and lower control limits if samples of size 6 are to be used.
