A chemical production process consists of a first reaction with an alcohol and second reaction with a base. A factorial experiment with three alcohols and two bases was conducted with four replicate reactions. The collected data were percent yield and shown in table below. i. Define two-factor factorial design. (2 MARKS) ii. State the advantages and disadvantages of factorial design? (4 MARKS) iii. Is there any indication that the interaction of the alcohol and base influences the yield? Use =0.05. (18 MARKS) iv. Use Turkey's test at the =0.05 to determine which alcohol result the difference in the yield percentage using base 2. (12 MARKS)
