Question

A factory produces light bulbs, and the time between failures is recorded in hours. The recorded times between failures are 1500, 2000, 800, 1500, and 2100 hours. Assuming that the time between failures follows an exponential distribution, what is the average time between failures? What is the probability that a light bulb will fail within the first 1500 hours after being put into service?

Step 1

The times between failures are 1500, 2000, 800, 1500, and 2100 hours. Mean (MTBF) = (1500 + 2000 + 800 + 1500 + 2100) / 5 Mean (MTBF) = 8000 / 5 Mean (MTBF) = 1600 hours Show more…
