There are a total of 10 test stations. When a circuit board fails, the test station will automatically record the lifetime for the failed board and then immediately switch to a replacement board. The test was stopped at 1200 hours. At that time, 19 circuit boards had failed and there was an operating circuit board in every station. Assuming the boards have exponentially-distributed lifetimes, estimate the mean lifetime for this type of board. State your answer rounded to the nearest hour.

40 circuit boards are put on test and the test is ended at 200 hours. Circuit boards that fail are not replaced. At 200 hours, 21 boards have failed. The sum of the fully observed lifetimes is 2,845 hours. Compute the maximum-likelihood estimator of the mean lifetime, assuming that the lifetime for this type of item has an exponential distribution. State your answer rounded to the nearest whole hour.
