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 of8 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 of8 integer values between 0 and 10000 Reset Selection Question 2 of8 0.1 Points Click to see additional instructions (b) Suppose 7 of the sampled lamps reach 10000 working hours.
