14) A factorial experiment was conducted to understand the impact of 4 inputs on the flex rate of a product in pounds per inch (the response variable). The goal was to increase the flex rate of the product. The inputs are: Factor A: Formulation (formulation 1 or formulation 2), Factor B: Cycle time ( 15 seconds or 25 seconds), Factor C: Pressure ( 300 psi or 375 psi) and Factor D: Temperature ( 110 degrees F or 130 degrees F). The data from the experiment are in the following table. Factor A Factor B Factor C Factor D Response 1 15 300 110 71 2 15 300 110 73 1 25 300 110 74 2 25 300 110 76 15 375 110 78 2 15 375 110 78 25 375 110 77 2 25 375 110 79 15 300 130 70 N 15 300 130 71 25 300 130 75 N 25 300 130 75 1 15 375 130 78 2 15 375 130 78 25 375 130 74 2 25 375 130 77 Use the following computer output to answer the questions.
