Answer 1

To obtain a random sample of lamps from the hotel, the ideal choice would be one that gives every lamp an equal chance of being selected.

The best option among those listed is:

100 lamps on each floor chosen randomly.

This method ensures that lamps from all floors are included in the sample, thus providing a more accurate representation of the entire population of lamps in the hotel. The other options either focus on specific room types or specific floors, which may not accurately reflect the overall condition of all the lamps in the hotel.
