Determine whether the underlined number describes a population parameter or a sample statistic. Explain your reasoning. Sixty-fi
ve of the 93 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.
Answer: A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.
Step-by-step explanation:
A population is simply similar items or events that a researcher or an experimenter is interested and wants to carry out an experiment on.
A statistic is simply referred to as the piece of information gotten from the population while a sample statistic is the piece of statistical information which a researcher will be able to get from the statistic.
In this scenario, the number is a sample statistic because it is a numerical description of all of the passengers that survived.
rs + st = rt Plug in the values 3x + 1 + 2x - 2 = 64 Combine like terms (1 and -2) 3x -1 + 2x = 64 Combine like terms (3x and 2x) -1 + 5x = 64 Add 1 to both sides 5x = 65 Divide both sides by 5 x = 13
