A sample of 10 electronic components was tested to a customer usage of 110 months. Seven of the ten components failed at times 89.6, 109.2, 79.2, 54.6, 83.0, 86.5, and 29.1 months.

(a) Create a Weibull probability plot.

(b) Estimate when 30% of the population will not have failed.

(c) Estimate the parameters of the distribution.

(d) State the most likely failure mode (i.e., early-life, intrinsic, wear-out).
