State the hypotheses and include any information used to conduct the test... b) Given that R² = 0.09, what is the correlation of heights in this data set? c) You meet a married man from Britain who is 5'9" (69 inches). What would you predict his wife's height to he? How reliable is this prediction? d) You meet another married Brit who is 6'7" (79 inches). Would it be wise to use the same linear model to predict his wife's height? Why or why not?

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 sample.
