Multiple choice six-sigma green-belt

As the Process Sigma increases ________-

  1. Number of defects increase exponentially

  2. Number of defects increase linearly

  3. Number of defects increase following quadratic equation

  4. None
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

As Process Sigma increases, the number of defects decreases exponentially, not increases. Higher sigma means better process capability with fewer defects. Option D 'None' is correct because all other options incorrectly state that defects increase. At 6 sigma, defects are extremely low (3.4 per million opportunities).
