A Full Factorial experiment using a 2 level 4 factor approach has been proposed to test the viability of an extrusion machine experiment. How many treatment combinations will this approach involve?

  1. 8
  2. 16
  3. 32
  4. 64

Answer(s): B



Which statement(s) are correct about the Factorial Plot shown here? (Note: There are 3 correct answers).

  1. When the cutting speed increased from low to high level, the tool age increases
  2. The coefficient of the metal hardness is positively related to the output of tool age
  3. The coded coefficient is lower for cutting speed than the cutting angle related to the output of tool age
  4. These plots prove a statistically significance factor with 95% confidence
  5. These plots are an example of interaction plots

Answer(s): A,B,C



Which statement(s) are incorrect for the Regression Analysis shown here? (Note: There are 2 correct answers).

  1. The air-fuel ratio explains most of the TurbineOutput variation
  2. The Regression explains over 98% of the process variation
  3. This Multiple Linear Regression has three statistically significant independent variables
  4. If the air-fuel ratio increases by 1, the TurbineOutput more than triples
  5. The SteamExitTemp explains the most variation of the TurbineOutput

Answer(s): D,E



Fractional Factorial Designs are used to analyze factors to model the output as a function of inputs if Hypothesis Testing in the Analyze Phase was inadequate to sufficiently narrow the factors that significantly impact the output(s).

  1. True
  2. False

Answer(s): A
