Question
The lifetime of LCD TV sets follows an exponential distribution with a mean of 100,000 hours. Compute the probability a television set:
a. Fails in less than 10,000 hours. (Round your answer to 4 decimal places.)
b. Lasts more than 120,000 hours. (Round your answer to 4 decimal places.)
c. Fails between 60,000 and 100,000 hours of use. (Round your answer to 4 decimal places.)
d. Find the 90th percentile. So 10% of the TV sets last more than what length of time? (Round the value to nearest whole number.)
