Question
You’ve looked at a scatter plot. Next you move on to looking at Best subsets. Based on the output below, which independent variables would you consider for your model? Why? (Your answer should include the decision criteria used to evaluate R2 , R2 (adj), R2 (pred) and Cp.)

The preffered model is
y Vs pluse1, Ran, sex and height
Since R2 is high and also standard error in low compare to all models
