Hotel maintenance crew wants to estimate how many of the 12000 lamps in their 30 story hotel need a new light bulb

1 answer

To estimate how many of the 12,000 lamps in the hotel need a new light bulb, the maintenance crew can conduct a sample inspection of a certain number of lamps throughout the building.

They can randomly select a representative sample of lamps from different floors and rooms in the hotel to determine the percentage of lamps that need a new light bulb.

Based on this sample inspection, they can calculate the percentage of lamps that need replacement and then apply that percentage to the total number of lamps in the hotel to estimate the total number of lamps that need a new light bulb.

For example, if a sample inspection of 300 lamps reveals that 15% of them need a new light bulb, the maintenance crew can estimate that approximately 15% of the 12,000 lamps in the hotel need replacement, which would be 1,800 lamps.

This estimation can help the maintenance crew plan their resources and schedule maintenance tasks efficiently.
