Chapter , Problem 10.41(choose chapter or problem)
Predicting the lean in 2013. Refer to the previous two exercises. PISA (a) How would you code the explanatory variable for the year 2013? (b) The engineers working on the Leaning Tower of Pisa were most interested in how much the tower would lean if no corrective action was taken. Use the least-squares equation to predict the towers lean in the year 2013. (Note: The tower was renovated in 2001 to make sure it does not fall down.) (c) To give a margin of error for the lean in 2013, would you use a confidence interval for a mean response or a prediction interval? Explain your choice.
