HELP - 1 hour and still no answer -- 2k factorial statistics : design experiment involving two factors to determine individual and interaction effect. use f-distribution to test hypothesis.

Q - What are the the null and alternative hypotheses to be tested?

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

Use same format as 2-way ANOVA except for 2 treatments?
