1) Distinguish between the terms population and sample. A complete response should include the definition for each and examples that demonstrate the difference between the two. (Let's try and use an example where the sample has a reasonable chance of being representative of the population.)
2) Distinguish between the terms parameter and statistic. A complete response should include the definition for each and examples that demonstrate the difference between the two. (Let's not use the example the size of the population and the size of the sample.)
3) Distinguish between the random sample and simple random sample.A complete response should include the definition for each and examples that demonstrate the difference between the two. (Examples here can be difficult. Let's see what you can do.)
