  4. A recent survey of approximately 400,000 employers reported that the average starting salary for marketing majors is $53,400. Determine whether the numerical value describes a population parameter or asample statistic.Explain your answer.

  5. Because the average of $53,400 is based on a subset of the population, it is a sample statistic.

  6. Determine whether the numerical value describes a population parameter or a sample statistic. Explain your answer. The freshman class at a university has an average SAT math score of 514.
