4) Now that Continental can detect more defects before the Silver Box is shipped, I decided process Improvements in its circuit board fabrication department would further improve quality. So, for one process they collected the following data this morning to set up a mean control chart. Since the process mean is unknown, estimate the mean and find the UCL and LCL for a 3-sigma mean control chart using this morning's samples. Sample 1 - 24, 24, 25, 22, 21 Sample...
