[AI-generated answer — Bot GPT 3.5]

To obtain a random sample of lamps to be inspected, the maintenance crew could use the following method:

1. Randomly select 10% of the total lamps for inspection. This would involve randomly selecting 1200 lamps out of the 12000 total lamps in the hotel for inspection.

2. Another approach could be to randomly select a certain number of lamps from each floor to ensure a representative sample from all areas of the hotel. For example, randomly select 40 lamps from each floor (assuming an average of 40 lamps per floor) for a total of 1200 lamps to be inspected.

These methods will help the maintenance crew obtain a random sample of lamps for inspection to estimate how many need a new light bulb in the hotel.
