A lamp manufacturer launches a new type of emergency lamps. Its durability is to be tested by checking how many of 8 randomly sampled lamps work for 10000 hours.

(a) What are the possible outcomes of the experiment?

• A.

The number of working hours each lamp reached:

a sequence of 8 real values > 0 (with no fixed upper bound)

• B.

The number of sampled lamps which reached 10000 hours:

0, 1, 2, 3, 4, 5, 6, 7, 8

• C.

The maximum working hours reached by the 8 lamps:

single integer values > 0

• D.

The number of working hours each lamp reached:

a sequence of 8 integer values between 0 and 10000
