(pages 577,59l).The MINITAB printout for the first-order model relating gosling weight change y to digestion efficiency x, and acid-detergent fiber x, ic reproduced above. Both a confidence interval for E(y)

and a prediction interval for y when x, = 5% and x, = 30% are shown at the bottom of the printout.

a. Interpret the confidence interval for E(y).

b. Interpret the prediction interval for y.
