Using the given random number table, the first customer arrives at 8:01 a.m. and requires 2 minutes of service. Therefore, the first customer finishes transacting business at 8:03 a.m.

To determine when the second customer finishes transacting business, we need to know the arrival time of the second customer. Using the given random numbers 95 and 08, we consult Table 13-4 to find the time between arrivals. Starting with the first random number 95, we go to row 95 and the second column which gives us a value of 3. This means that the second customer arrives 3 minutes after the first customer. Adding this to the arrival time of the first customer (8:01 a.m.), we get the arrival time of the second customer: 8:04 a.m.

Using the given random numbers for service times (92 and 18), we consult Table 13-4 to find the service time for each customer. Starting with the first random number 92, we go to row 92 and the second column which gives us a value of 2. This means that the first customer requires 2 minutes of service. For the second customer, starting with the next number in the table after 92 (which is 54), we go to row 54 and the second column which gives us a value of 4. This means that the second customer requires 4 minutes of service.

Adding the service time of the second customer (4 minutes) to their arrival time (8:04 a.m.), we get the time at which they finish transacting business: 8:08 a.m.

Therefore, the correct answer is choice C, 8:09 a.m.
