Question

determine whether the underlined number describes a population parameter or a sample statistic. explain your reasoning. sixty - seven of the 98 passengers aboard an airship survived an explosion. choose the correct statement below. a. the number is a sample statistic because it is a numerical description of all of the passengers that survived. b. the number is a population parameter because it is a numerical description of all of the passengers that survived. c. the number is a population parameter because it describes the people in the airship, which is a subset of all people. d. the number is a sample statistic because it describes the people in the airship, which is a subset of all people.

Explanation:

A population parameter describes an entire population. Here, the 98 passengers on the airship are the entire population of interest (the group we are studying regarding the explosion). The number 67 represents the number of survivors in this entire population. So, it is a numerical description of all the passengers that survived within this defined population.

Answer:

B. The number is a population parameter because it is a numerical description of all of the passengers that survived.
