The underlined numerical value 8% is a parameter because the data set of all 843 animals in a zoo is a population.
Option B is correct.
What is the difference between a parameter and a statistic?
In quantitative research, numerical data are gathered and analyzed to identify patterns, identify relationships, or test hypotheses.
A statistic is a number that describes a sample i.e. sample mean, whereas a parameter is a number that describes the entire population (such as the population mean). Identifying the population parameters helps quantitative research understand population patterns.
From the given information:
The underlined numerical value is a parameter. This is because the data set of all 843 animals in a zoo is a population.
It implies that:
- The total population of all animals in the Zoo = 843
- The proportion = 8%
Thus, it is the ratio concerning the population. As such, 8% is population proportion(Parameter).
