Random error.
A sample of a population is a subset of the population. The average of the population is a statistical measure for some variable of the population.
You can use the z test for two proportions. The link below will do this test for you.

Statistical sampling is an objective approach using probability to make an inference about the population. The method will determine the sample size and the selection criteria of the sample. The reliability or confidence level of this type of sampling relates to the number of times per 100 the sample will represent the larger population. Non-statistical sampling relies on judgment to determine the sampling method,the sample size,and the selection items in the sample.
What is the difference between the population and sample regression functions? Is this a distinction without difference?
A sample of a population is a subset of the population. The average of the population is a statistical measure for some variable of the population.
Population refers to all the individuals or items of interest in a particular group. Statistical population refers to the theoretical concept of all possible individuals or items that could be included in a study, from which a sample is actually drawn. Statistical population is typically larger than the actual population being studied.
Statistical: must have random sampling, allows you to generalize to the population from which you randomly selected. Practical: do the results hold for similar individuals? allows you to generalize to similar individuals
Homogeneity means that the statistical properties of the variable which is being studied remain the same across the population. Heterogeneity means that they do not: it could be that the mean changes between different subsets of the population or the variance does.
Explain the difference between capability and control.

differances between stationary population and stable population
The difference in between an individual, a population, a community, and an ecosystem is and individual (also known as an organism) is only one thing. The difference in between an an organism and a population is a population is multiple organisms. The difference between a population and a community is a group of populations make a community which of course makes a whole ecosystem.
