Question

A researcher seeks funding for a study from a federal agency. The study will involve the evaluation of three factors, each having two levels. From the literature, the researcher approximates the standard deviation in the responses to be approximately 9 units. How many experimental units should be included in the budget for the study so that a difference of 20 units or more in any pair of treatment means will be detected with a probability of .80 using an α = .05 test?
