Answer:
The registered passengers vehicle is he population and the one that are electro-gas hybrids forms a sample of the population.
Step-by-step explanation:
We are given the following in the question:
The U.S. Department of Transportation announces that of the 250 million registered passenger vehicles in the US, 2.1% are electro-gas hybrids.
Population and sample:
- Population is collection of all the observations of individuals of interest.
- Sample is a subset of population.
- Population is always larger than the sample.
- Population is the universal set of all observations.
Thus, for the given case,
Individual of interest:
250 million registered passenger vehicles in the US
Population of interest:
250 million registered passenger vehicles in the US
Sample:
2.1% electro-gas hybrids.
Thus, the registered passengers vehicle is he population and the one that are electro-gas hybrids forms a sample of the population.
