Consider a 25 factorial design with factors A, B, C, D and E. a. Suppose the 25 design was constructed in blocks so that the interaction effects ABC and ABDE are confounded with blocks. i) How many blocks are required for the experiment? Hence, determine the number of treatment combinations in each block. ii) What other effect is confounded with blocks? iii) An engineer uses an alternate design that confounds the interaction effects BDE and BCDE. Will this design yield proper results? Explain why or why not. [2+1+3]
