A hotel maintenance group wants to estimate how many of the 12,000 lamps and the 30 story hotel needs a new lightbulb which of the following is Random Sample of lamps to be inspected
To obtain a random sample of lamps to inspect, the hotel maintenance group could use a systematic random sample. Here is one example of how they could do this:
1. Assign a number to each lamp in the hotel (from 1 to 12,000).
2. Choose a starting point at random (for example, by picking a random number between 1 and 12,000).
3. Select every nth lamp to inspect (for example, every 100th lamp).
4. Continue this process until the desired sample size is reached (e.g. inspecting 100 lamps).
This method ensures that each lamp has an equal chance of being selected for inspection, making it a random sample.
