The sample mean may differ from the population mean, especially for small samples.
A representative sample is one where the statistics of the sample are the same as the statistics for the parent population.
Information obtained from the sample can be extrapolated to the whole population using statistics.

Inferential statistics.
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.
