Discuss the below:
Q: A unit of output is considered not defective if it's a) at least 130 cm long: but B) no more than 160 cm long. Suppose this process's standard deviation is 3.75 cm. For this process the control limits for the sample mean are:
UCL(x-bar) = 140
LCL(x-bar) = 142
How capable is this process?
