Additional Problem A researcher collected data on Y and four X-variables: X1, X2, X3, X4, and he wants to obtain a regression model. However, he is not sure if all the four X-variables should be included in the model. He provides you with the information shown below, namely, the SSR obtained when Y was regressed on each subset of X-variables. Also given: SST-100, and that the sample size is n 12.
