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: See the results of the experiment in Table \# 1 (BB Practical Exam Tables.xls). 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: Which experiments from the original list are used in the Fractional Factorial Design? (See numbering on the B column on the table.) a) 1,2,5,8,11,12,14 and 16 b) 2,5,7,8,10,12,13 and 16 c) 1,3,6,8,11,13,14 and 16 d) 2,3,5,8,11,12,15 and 16 e) 1,4,6,7,10,11,13 and 16
