(Round your numerical values to two decimal places. Use x, for minimum width, x₂ for the r 302 (b) Why should we consider adjusted R² instead of R2 when evaluating this model? O We should consider the adjusted instead of 2 because it takes into account the number of predictors used in the model. In this case the adjusted is noticeably less than ². ² instead of r² because it does not take into account the number of predictors used in the model. In this case the adjusted ² is noticeably greater than ². instead of because it does not take into account the number of predictors used in the model. In this case the adjusted is noticeably less than 2. instead of 2 because it takes into account the number of predictors used in the model.

We have convincing evidence that the multiple regression model is useful and can conclude that ₁, ₂ and 6 are all not 0. O Reject H. We have convincing evidence that the multiple regression model is useful and can conclude that at least one of ₁, ₂ or 3 is not 0. O Fail to reject H. We do not have convincing evidence that the multiple regression model is useful and cannot conclude that ₁, ₂ and ₂ are all not 0. O Fail to reject Ho- We do not have convincing evidence that the multiple regression model is useful and cannot conclude that at least one of B₁, B₂ or B₂ is not 0.
