Explanation / Answer
The statement that "A process is capable if special cause variations are below the center line" is TRUE. The process is said to be capable when all the measurements are below the set specification limits. When we compare the results of a stable process with the standard set of specification for the process we conclude that if the results are below the centreline than the process will be considered as capable.
