  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.

  7. Because the average SAT math score of 514 is based on the entire freshman class, it is a population parameter.

  8. In a random check of 400 retail stores, the Food and Drug Administration found that 34% of the stores were not storing fish at the proper temperature. Determine whether the numerical value describes a population parameter or asample statistic. Explain your answer.
