Accident records on a highway segment are reported in the form of times between accidents. The following record was established in days: 2, 3, 1, 3, 2, 5, 1, 2, 3, 4, 3, 1, 1, 2, and 2. Assume an exponential distribution. Compute the average time between accidents? What is the probability that the time between consecutive accidents would exceed 2 days? What is the probability that the time between consecutive accidents would exceed 5 days?
