Answer:
51
21
Step-by-step explanation:
Let x be larger number
Let y be smaller number
x - 2y = 9
==>
x = 9 + 2y
AND
x + y = 72
SO
(9 + 2y) + y = 72
==>
3y = 72 - 9 = 63
==>
y = 21
SINCE
x = 9 + 2y = 9 + (2×21)
==>
x = 51

Answer:
A. The population in the CPS survey are all US households.
B. The population in the CES survey are all the non-farm businesses and government agencies.
Step-by-step explanation:
A sample is the number of people from a whole population who actually participated in a survey. The population is the entire group of people whom the survey is meant to study. The sample is an off shoot of the population.
In the given question, the Current Population Survey is a study on the entire US households. Since every household cannot be interviewed because of the large population, a sample of 60,000 households is used. The whole households in the United States thus form the population under study.
For the Current Employment Statistics survey, the goal is to understand employment statistics in all the non-farm businesses and government agencies. This is the population. Since the entire population cannot be studied, a sample of 140,000 is used.
