Read the 3 problems provided below:

1. A drill press operator drills 10 holes into a plate of titanium that is used on a fighter plane. The quality department measures the holes in every fifth plate to ensure the diameter is within specifications. What type of experimental design (see Design of Experiments in your textbook) would you use to determine if the holes are within specifications - one-factor, two-factor, or three-factor design? Support your answer.
2. Two different operators answer service calls for a computer manufacturer during the same shift. The quality department monitors the service call times and would like to determine if the service call time is affected by the operator. What type of experimental design (see Design of Experiments in your textbook) would you use to determine if the operators affect the service call time - one-factor, two-factor, or three-factor design? Support your answer.
3. A tire dealer has 3 service personnel that install tires on the same shift. The quality department records the service times and would like to determine if the service time is affected by the service person. What type of experimental design (see Design of Experiments in your textbook) would you use to determine if the service time is affected by the service person - one-factor, two-factor, or three-factor design? Support your answer.
4. Write a 1-2 page document that includes your responses to all 3 problems of experimental design. Support your answers with information from your assigned reading or any additional academic resources you have located. Cite your resources in APA format.
