Answer:
Step-by-step explanation:
In this scenario:
- The homeowner measured the voltage supplied to his home on 288 days.
- The average (mean) value of these measurements is 101.1 volts.
The value "101.1 volts" in this context is a **statistic**. A statistic is a numerical value calculated from a sample (in this case, measurements taken on 288 days). It is used to describe a characteristic of that sample.
If this value represented the average voltage for the entire population of homeowners in the area, it would be a **parameter**. Parameters describe characteristics of an entire population.
