Question:

Refer to Exercise 17.19.

a. Use the estimates of α and β to find the probability that a memory chip will fail before 5 years.

b. Estimate the reliability of the memory chips at time t = 7 years.


Data from Exercise 17.19

Suppose the life length (in years) of a memory chip in a mainframe computer has a Weibull failure time distribution. To estimate the Weibull parameters, α and β, 50 chips were placed on test and the number of survivors was recorded at the end of each year, for a period of 8 years. The data are shown in the accompanying table.
