The general form of an interval estimate of a population mean or population proportion is the <u>point estimate </u>plus or minus the <u>margin of error</u>.
<u>Explanation:</u>
An interval estimate is used to estimate a population parameter by using sample data. The margin of error can be decreased by increasing the sample size. The interval estimate of a population mean or population proportion is the point estimate plus or minus the margin of error.
A convenience sample is used from the members of the population because they are easily accessible. A population proportion defines the percentage value of the population. The sampling distribution represents the probability distribution showing all possible values of the sample mean.

Population density is the number of people per unit of area, usually quoted per square kilometre or square mile, and which may include or exclude for example areas of water or glaciers. Commonly this may be calculated for a county, city, country, another territory or the entire world.
