14. A 25-2 design is defined by 4 13 and 5 23. (a) Find its defining words and resolution. (b) After the analysis, variable 5 turns out to be inert. It is assumed that all two-factor interactions involving variable 5 and all higher order interactions are negligible. In addition to estimating the four main effects, there are st three degrees of freedom left. What two-factor interactions can be estimated with these three degrees of freedom?
