lines are busy? Binomial Distribution. Thus, option b is the correct
answer.

implementation of the first team. Control is not an insignificant phase of the
four phases of DMAIC? DMAIC process. The green belt or the process owner
alone may not have the ability and knowledge to
structure the last control step. So option d is correct.
A. The green belt alone;
