Suppose we are observing a process such that the time between occurrences is exponentially distributed with λ = 1/30 (i.e., the average time between occurrences is 30 minutes). Suppose that the process starts at a certain time and we start observing the process 3 hours later. Write a program to simulate this process. Let T denote the length of time that we have to wait, after we start our observation, for an occurrence. Have your program keep track of T . What is an estimate for the average value of T ?
