Have X= 1, 4, 3, 2, 5, 6, 0. and Y= 1, 3, 3, 1, 4, 7, 2. I get the least squares equation as y=15/28+23/28x. is it correct? How do I test whether the model can be used for predicting Y? How much of the variation in T is explained by variation in X? What is the predicted value of Y given X=2.5 at 90% confidence level?
