*2.15. Refer to Airfreight breakage Problem 1.21. 216 a. Because of changes in airline routes, shipments may have to be transferred more frequently than in the past. Estimate the mean breakage for the following numbers of transfers: X = 2, 4. Use separate 99 percent confidence intervals. Interpret your results. b. The next shipment will entail two transfers. Obtain a 99 percent prediction interval for the number of broken ampules for this shipment. Interpret your prediction interval. c. In the next several days, three independent shipments will be made, each entailing two transfers. Obtain a 99 percent prediction interval for the mean number of ampules broken in the three shipments. Convert this interval into a 99 percent prediction interval for the total number of ampules broken in the three shipments. d. Determine the boundary values of the 99 percent confidence band for the regression line when Xh 2 and when X = 4. Is your confidence band wider at these two points than the = h corresponding confidence intervals in part (a)? Should it be? Defor to Dloctia hordnaco Problem 100
