Using your own height and the appropriate regression equation from
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?
