Statistic because the value is a numerical measurement describing a characteristic of a sample.

Step-by-step explanation:

The complete question is

Determine whether the underlined number is a statistic or a parameter. A sample of employees is selected and it is found that 35% own a television. Choose the correct statement below.

- Parameter because the value is a numerical measurement describing a characteristic of a population.

-Parameter because the value is a numerical measurement describing a characteristic of a sample.

-Statistic because the value is a numerical measurement describing a characteristic of a sample.

-Statistic because the value is a numerical measurement describing a characteristic of a population.

when the result is gotten from the population, the numerical measurement describing this result is known as the parameter. If the result is gotten from the sample(a fraction of the population), the numerical measurement describing this value is called a statistic.

From the question, the 35% was calculated from a selected sample of employers. The parameter would have been if the whole workforce in the country was actually analysed.
