A lumber processing operation cuts pine posts with a standard deviation in millimeters equal to the last two digits of your student ID. (For example, if your student id is 900123456, the process standard deviation would be 56 mm.) The specs for products at this stage are 2500 140 mm.

As owner of this business, a family board reduces your personal end of year bonus based on the number or customer returns over 0.3%. Based on results from part b), prioritize among the following three possible actions and indicate the expected impact of each action and your reasoning for the plan. (Assume youd like to maximize your personal end of year bonus, but recognize that the cost of improvements ultimately also comes out of your own pocket due to family ownership of the business.)

1.Inspect the finished posts (for conformance to specifications) prior to shipment.

2.Work to reduce the process standard deviation.

3.Adjust the process mean.
