The statistical thinking underlying Six Sigma is based on which of the following three principles?

All work is a statistically controlled process, $100\%$ control is always possible, and every well$-$controlled process is error$-$free

All work is a process, all processes have "variability", and all processes create data that can explain the variability

All work activities can be done accurately most of the time, empowered employees are necessary for effective control, and good statistical data is an empowered employee's best control tool

Most business processes are controllable, and Six Sigma can totally remove any variation in those processes so that defects are eliminated.

All activity can be controlled, employee empowerment is the best control tool, and $100\%$ control is possible
