1. When a process is capable, the following is going to happen
   1. CL-3=0
   2. USL-3=0
   3. Max[((USL- )/3) ; ( - LSL)/ 3 ] >1
   4. Min[((USL- )/3) ; ( - LSL)/ 3 ] >1
   5. None of the above
2. The X chart shows all the sample averages within control limits. The R chart does the same but there is a constant positive trend for the ranges as time goes by. This means
   1. The process is out of control
   2. The process is under control
   3. The process is under control but I should be vigilant and watch it closely
   4. The process is under control but I should increase the sample size from now on and keep checking because with a larger sample chances are I will see there is assignable variation
   5. I made a mistake in choosing factors D3 and D4
3. The demand forecast overestimates demand and there is a safety stock. Then the CSL will be
   1. CSL = 50%
   2. CSL < 50%
   3. CSL >50%
   4. CSL = 100%
   5. More information is needed to decide
