yes the size is 4444
How is a sample related to a population?
A sample is a subset of the population.
What is a random sample from a population?
A random sample is a sample (subset of the population) where each member of the population has an equal chance of being sampled. See related links.
If the sample mean is 10 the hypothesized population mean is 9 and the population standard deviation is 4 compute the test value needed for the z test?

A representative sample.
Which type of sample is selected to reflect the demographic characteristics of the population of interest?

A sample is any subset of the total population. A representative sample is one that is chosen so that its characteristics are similar to that of the population.
Why is it so important to have a representative sample?
If the sample is not representative of the population, then the characteristics of the sample are not the characteristics of the population. Example: If I want to estimate the percentage of the population that are men, and my sample is the school's football team, my estimate would be that 100% of the population is comprised of men. What went wrong with my survey ? Simple. The football team is not a representative sample of the population, at least not as regards gender.

Why are you using sampling?
Usually we are interested in the characteristics of large populations of items or people. It would often prove costly or impossible to measure these characteristics for the entire population. We therefore measure them for a carefully selected sample of the population and attempt to make scientific inferences about the entire population from the characteristics of the sample.
Does the accuracy of a sample in representing the characteristics of the population from which it was drawn always increase with the size of the sample?
yes the size is 4444
