Using your own height and the appropriate regression equation from Exercise 10.19 or 10.20, predict your own weight. (If you are uncomfortable reporting your own weight, predict mine— I am 5980 and weigh 156 pounds—well, at least I would like to think so.)
(a) How much is your actual weight greater than or less than your predicted weight? (You have just calculated a residual.)
(b) What effect will biased reporting on the part of the students who produced the data play in your prediction of your own weight?
