This is one academic question, although it has several parts. So, answer what is allowed, and I will reask the question as needed.
An experiment is to be conducted with five treatment groups: A, B, C, D, and E. Write down linear contrast expressions for testing:
(a) if the average of group means for A and B equals the average of group means for C, D, and E;
(b) if the group means for A and B are equal;
(c) if the average of group means for C and D equals the group
(d) if the group means for C and D are equal.
(e) Are the first three linear contrasts mutually orthogonal? Can all four linear contrasts be mutually orthogonal? Explain.
