Choose the correct statement below. a. Statistic because the value is a numerical measurement describing a characteristic of a sample. b. Statistic because the value is a numerical measurement describing a characteristic of a population. c. Parameter because the value is a numerical measurement describing a characteristic of a sample. d. Parameter because the value is a numerical measurement describing a characteristic of a population.

Answer 1

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

Step-by-step explanation:

Given : A sample of students is selected and it is found that 25 % own a television.

A parameter is a measure that is evaluated from the whole population like population mean , population proportion  , so it represents the entire population where as a statistic is a measure evaluated from a sample taken from population, so statistic represents the sample.

Since , 25% represents the proportion of students own a television in the sample.

∴ 25% represents the statistic.

Hence, the correct answer is  

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