In order to maximize filtration flow, a company conducts an experiment to learn more about the optimal operating conditions when filtering a chemical product. The four factors that were analyzed and their respective levels are the following: BB Practical Exam Tables A) Create a 4-1 fractional factorial design to reduce the number of necessary experiments by half. B) With the 4-1 fractional factorial design, and using the data from the previous table, answer the following question: What are the significant factors of this operation and in what order (from most significant to least significant)? IMPORTANT NOTE: Download the attached file (BB Practical Exam Tables) and use it to answer the next questions. a) D,B,BC,BD and C b) A,CD,BD,B and D c) C, AC, BD, A and D d) A,AD,AC,C and D e) D,A,BC,BD and AC
