Expert Solution

Statistical sampling requires a representative sampling objective in which each population unit must have an predictable chance of selection. In non-statistical sampling there is no guarantee that each population unit has a predictable chance of being selected. Note, however, that a population unit depends on how a population is defined. For example, an accounts receivable population can be viewed as a population of accounts, each account potentially having different values. Or the accounts receivable can be viewed as a population of dollar (monetary) units, with each unit having exactly the same value. This illustrates that even when using “scientific” statistical methodology we are still applying critical thinking concepts such as effect of perspective.

Sampling and sampling distributions are the basis of statistical analysis, and they are also important parts of applied business statistics. Therefore, designing an effective sampling plan is crucial to get representative samples of the population under study. Explain the role that a sample plays in making statistical inferences about the population. Give an example of a sampling survey for a business study, and briefly discuss how the projected sampling results could have an effect on the business’ pricing strategies and...
