Insulating fluid. Table 2.1 of Chapter 7 shows samples of times to breakdown of an insulating fluid at five test conditions. According to engineering theory, these distributions are exponential
(a) Separately plot each of the five samples on the same sheet of Weibull probability paper.
(b) Graphically estimate the five shape parameters.
(c) Do the shape parameters appear comparable, subjectively taking into account the randomness in the data?
(d) Do exponential distributions adequately fit the data?
(e) Are there any peculiarities or other noteworthy features of the data
