You work for a consumer group that has decided to examine this claim.Technicians ran 16 drives continuously for three years. Recently the last drive failed. The time to failure (in hours) are given below.

Time Until Failure (Hours)
330 1870 2410 4620 6396 7822 8102 620
8309 12,882 14,419 16,092 18,384 20,916 23,812 25,814
