Given a simple regression analysis, suppose that we have obtained a fitted regression model:
hat(Y)=10+3x and we are given: hat(\sigma )=10,\bar{x} =10,n=32 and \sum (x_(i)-(\bar{x} ))^(2)=500
a95% confidence interval of Prediction for E_(_())((Y)/(x)=20), that is x_(\Omega )=20.
bR^(2) of the above estimated model.
