In regression analysis, if you know that the coefficient ofdetermination is R2 = 0.40 when X1 is used to predict Y, and R2 =0.42 when X2 is used to predict Y, then it should be possible todetermine the possible range of R2 values when both X1 and X2 areused to predict Y. What is the possible range for R2 in thetwo-predictor model?
