Name the scale of measurement for each of the above variables

Determine whether the given value is a statistic or a parameter. A homeowner measured the voltage supplied to his home on a random sample of 48 days, and the average (mean) value is 122.9 volts. Choose the correct answer below. OA. The given value is a statistic for the year because the data collected represent a sample. OB. The given value is a parameter for the year because the data collected represent a population. OC. The given value is a parameter for the year because the data collected represent a sample. OD. The given value is a statistic for the year because the data collected represent a population.
