The process capability ratio, Cp, of a process is 0.70. You are required to determine the fraction of defective products. And in that calculation you need to calculate Z (UTL) and Z (LTL). What would be Z (LTL) = ? Round your answer to TWO places of decimal. Question 5 15 pts A process has a process capability ratio, C =1.38. At some time the process seems to have a mean shifted left of the center. The process capability index.Cok. is found to be 0.78, and the mean is left-shifted, that is the current mean is mess than the mean of the control chart. Determine the Z (UTL) with respect to the current left-shifted mean.
