1.
For x: 3, 5, 7, 9 and y: 12, 10, 6, 2, is the prediction of y at x = 11 reliable?
Yes, because the line passes through (x̄, ȳ)
Yes, because r is close to −1, which guarantees accuracy
No, because regression is never used for prediction
No, because it is extrapolation outside the data range and gives an unreasonable negative value
