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.
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
WHAT DOES X BAR MEANS IN STATISTICS?
In statistics, "x-bar" (denoted as (\bar{x})) represents the sample mean, which is the average of a set of values in a sample. It is calculated by summing all the observations in the sample and dividing by the number of observations. The sample mean is used to estimate the population mean and is a key concept in inferential 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.
