You test some components with a Weibull distribution at temperatures of 100 Celcius and 60 Celcius. At those temperatures you estimate a characteristic life of 15000 hours and 25000 hours respectively. hint: Boltzmann's constant is k = 8.617 105. Temperature in Celcius + 273.15 = temperature in Kelvin. If n is an integer, (n) = (n 1)!
a) Using linear regression, estimate the Arrhenius model parameters A and H. b) Give the MTTF, median, and 90th percentile at T = 20 Celcius. Assume that the shape parameter is 0.5.
