What is represenatative sample of population?
A representative sample is one where the statistics of the sample are the same as the statistics for the parent population.
What is the relationship between a sample and population is statistics?
Information obtained from the sample can be extrapolated to the whole population using statistics.
What are Pros and Cons of population and sample in statistics?

Are the sample mean and sample proportion of a population are called population parameters?
No, the sample mean and sample proportion are not called population parameters; they are referred to as sample statistics. Population parameters are fixed values that describe a characteristic of the entire population, such as the population mean or population proportion. Sample statistics are estimates derived from a sample and are used to infer about the corresponding population parameters.
What type of statistics employ the use of sample data that is used to infer information about the population?
Inferential statistics.

Inferential statistics. This branch of statistics involves making inferences or predictions about a population based on data collected from a sample taken from that population.
