Discussion Questions

Calculate the control charts $($ UCL,$CL,$ and $LCL$ for each operator$-$machine combination separately. Do this for both $x-$bar $($average$)$ and range charts. What conclusions can you draw from the charts about each operator$-$machine combination?

What should be done based on the calculations from question $1?$

What is the process capability for each operator$-$machine combination?

Can you be sure that every part produced by in$-$control processes will meet the specification?

Identify and explain any underlying assumptions for the calculations done here.
