Final answer:
A process in statistical control does not guarantee that all or nearly all of the product units will be within the specification limits, but it means that the process is stable and predictable. There may be some variation, but it is within acceptable limits.
Step-by-step explanation:
When a process is considered to be in a state of statistical control, it means that the process is stable and predictable. However, it does not guarantee that all or nearly all of the product units produced will be within the specification limits. In a state of statistical control, there may still be some variation in the product units, but the variation is within acceptable limits.
For example, in a manufacturing process, if the specifications for a product are that it should weigh between 10-12 ounces, a process in statistical control would mean that most of the product units will fall within this range. However, there may still be a few units that fall slightly outside the range, but these deviations are considered to be within normal process variation.
