To compute the test value for the coffee machines, you need to calculate the average amount of coffee dispensed by the three machines. Here's how you can do it:

1. Add up the amounts of coffee dispensed by each machine: 2.25 + 5.06 + 6.62 = 13.93.
2. Divide the total amount by the number of machines (in this case, 3): 13.93 / 3 = 4.6433 (rounded to four decimal places).
3. The test value for the coffee machines is the average amount of coffee dispensed by the machines. In this case, it is approximately 4.6433.

Therefore, the test value for the coffee machines is 4.6433, or you can round it to 4.64.
