This is the question and my solution, can you tell if it is
right and if it is wrong, how can it be corrected? Thank you so
much for your help,
Question 5: It is believed that the strength of some alloy depends on its carbon, C, molybdenum, Mo, and nickel, Ni, contents. The levels of C are 0.03 and 0.07, the levels of Mo are 0.01 and 0.05, and those of Ni are 0.1 and 0.2. (a) Suppose one half of the design is run and C-Mo is the generator. Write down the combinations that will appear in the principal fraction. (b) Suppose one forth of the design is run and C-Mo and Mo-Ni are the generators. Write down the aliases for main effects and two-factor interactions. (c) What is the resolution of the design in part (b), Answer:
