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 34 dayson a random sample of 34 days , and the average (mean) value is 136.4136.4 volts. Choose the correct answer below.

A. The given value is a statisticstatistic for the yearyear because the data collected represent a populationpopulation.

B. The given value is a parameterparameter for the yearyear because the data collected represent a samplesample.

C. The given value is a statisticstatistic for the yearyear because the data collected represent a samplesample.

D. The given value is a parameterparameter for the yearyear because the data collected represent a populationpopulation.

    C. The given value is a statistic for the yearyear because the data collected represent a samplesample.

    Explanation:

    A parameter is a numerical measurement of a population while a statistic is a numerical measurement of a sample. Statistics use assumptions to represent relations among variables and parameters should meet requirements and present more objective data. In this case, the voltage value found is the mean of a 34 days sample and, therefore, the given value is a statistic of the daily voltage for the year.

The potential energy of two atoms in a molecule can sometimes be approximated by the Morse function, U (r) = ARe (R-01.5 - 1) 2 where r is the distance between the two atoms and A, R, and S are positive constants with S << R.
