Use color-coding or divinet symbols to divingwith the groups OA OB. De Does the coding explain an wrowal aspect of the "black and white" scatterplot? C A. The outing indicates that the groups offer OB. The Mixing indicates that each group has the same variation C C. The Doing ineleven that the groups are similar. to) Assuming that the model meets the conditions for the MAM, use the incremental F-tend to assess the size of the change in Ry. (The value of thus for the model with dummy and interaction in 3, with 3 slopes added. You willneed to fit the simple regression to get its It" for comparison to the multiple regression.) The critical value for the incremental F-bast is 4. Calculate the F-abadivic. FRound to two decimal Does the lest agree with your visual impression? O) A. No. this does not agree with Be sort is sufficient. O B. Yes, this agrees with the visual impression. The added C C. No, this does not agree with the visual impression. This test Inchoates that the added variables are intenlly significant and the simple regression is sufficient.
