Explain why it can be dangerous to use the least-squares line to obtain predictions for x values that are substantially larger or smaller than those contained in the sample. The least-squares line is based on the x values Select the sample. We do not know that the same linear relationship will apply for x values -Select- the range of values in the sample. Therefore the least-squares line should not be used for x values -Select- the range of values in the sampl
