Snow geese feeding trial. Refer to the Journal of Applied Ecology study of the feeding habits of baby snow geese, Exercise 4.10 (p. 186). Recall that a ?rst-order model was used to relate gosling weight change (y) to digestion ef?ciency (x1) and acid-detergent ?ber (x2). The MINITAB printout (top of p. 194) shows both a con?dence interval for E(y) and a prediction interval for y when
x1 = 40% and x2 = 15%.
(a) Interpret the con?dence interval for E(y).
(b) Interpret the prediction interval for y.
