Insulating fluid. Use the first nine times to breakdown of the 30-kV data of Table 2.1.
(a) Calculate an upper 90% prediction limit for the 10th failure time, assuming that time to breakdown has an exponential distribution.
(b) Do (a) assuming that time to breakdown has a Weibull distribution.
(c) Plot the 10 times to breakdown on Weibull or exponential probability paper.
(d) Comment on an appropriate analysis of the 30-kV data.
