State hypothesis for 2k factorial design

  1. Jun 8, 2012 #1
    How to state null and alternative hypothesis for 2k factorial design of two factors?

    3. The attempt at a solution

    All i can think of right now is

    null hypothesis - Factor A effects not significant.
    alternative hypothesis - Factor A effects significant

    null hypothesis - Factor B effects not significant.
    alternative hypothesis - Factor B effects significant

    null hypothesis - interaction effects not significant.
    alternative hypothesis - interaction effects significant

    i think it is abit too simplistic, so i want to find out if there are other ways to express this or different notation.

    i need some way to express it in terms like
    Ho : τ1 = τ2 = τ3 ... τa =0
    Ha : at least one τi ≠ 0
    however i need equation that is suitable for this specific purpose

    is it just Ho : τ1 = τ2=0
    Ha : at least one τi ≠ 0
