Insulating fluid (Weibull). For the 38-kV data in Table 4.1, do the following, assuming that time to breakdown has a Weibull distribution.
(a) Estimate the Weibull parameters.
(b) Calculate twoLsided approximate 90% confidence limits for the shape parameter
(c) Estimate the 10th percentile.
(d) Calculate two-sided approximate 90% confidence limits for the 10th percentile.
(e) Plot the data and the estimate of the distribution on Weibull paper.
(f) Calculate two-sided approximate 90% confidence limits for other percentiles and draw smooth curves for the limits on the Weibull plot.
