Question

Quizplus · Accepted Answer

A process is considered stable when its mean and variance remain constant over time. This means that the process is predictable and can be controlled within its current state. Therefore, option C, stable, is the correct choice. Option A, in statistical control, means that the process is currently within its expected range of variability and is predictable. Option B, normally distributed, describes the shape of the data distribution and is not directly related to the stability of the process. Option D, capable, refers to the ability of the process to meet specific specifications and is also not directly related to process stability.
