Consider the time to failure data in Exercise 9.19. Is the normal a reasonable model for these data? Why or why not?
In exercise
Consider the following 20 observations on time to failure: 702, 507, 664, 491, 514, 323, 350, 681, 281, 599, 495, 254, 185, 608, 626, 622, 790, 248, 610, and 537. Is either exponential or the Weibull a reasonable choice of the time to failure
