A computer component life test of four randomly selected modems had failure times of 1.2, 2.7, 3.4, and 5.1 years.

(a) Create a Weibull probability plot.

(b) Estimate when 25% of the population will fail.

(c) Estimate the parameters of the distribution.

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