Please write clearly and thoroughly explain all your computations; an unannotated series of formulas that mysteriously ends up with the correct number will not be given full credit. When doing the homework, you are encouraged to use all resources at your disposal to the extent that they help you learn the material; nevertheless, you must write your own answers in your own words.

    p. 517, #7.
    Do the analyses in SPSS; include only the relevant output tables. Be sure to be clear about which table is for which part of the question and keep all the tables in sequence with your answers.

  2. (10 pts.)
    p. 518, #9, parts a and b (not c).
    Hint: For fixed factors A and B with random factor C, when testing the significance of A, use MSAxC as the error term. When testing the significance of AxB, use MSAxBxC as the error term.
