HELP Needed :))

Write out the complete table of + and - signs for the 3-factor factorial design with A, B, C (the table should have 8 rows for treatment combinations and 8 columns for effects including I). The treatment combinations should follow the standard order on P35 of L6. Then write out the Contrast for effect BC.

*** Lecture 6 Page 35 below ( Mentioned in Question):

Treatment Combinations In a 25 design abd denotes the treatment combination with factors A, B, and D at the high level and factors C and E at the low level. The standard order of treatment combinations: Introducing factors one at a time, with each new factor being successively combined with those that precede it. For example, the standard order for a 24 design is (1), a, b, ab, c, ac, bc, abc, d, ad, bd, abd, cd, acd, bcd, abcd.
