A Gallup Poll asked, "In general, how often do you experience stress in your daily life - never, rarely, sometimes, or frequently?"
Gallup's report said, "Results are based on telephone interviews with 1,027 national adults, aged 18 and older, conducted Dec. 6-9, 2007."
What is the population for this sample survey? What is the sample?
A.The population is the 1027 adults who were interviewed and the sample is adult U.S. residents.
B.The population is adult U.S. residents and the sample is the 1027 adults who were interviewed.
C.The population is adult U.S. residents and the sample is all those who responded "frequently".
D.The population is the 1027 adults who were interviewed and the sample is those who responded "frequently".
To determine the population and sample in this survey, we can analyze the information provided.
The Gallup Poll conducted telephone interviews with 1,027 national adults, aged 18 and older, between Dec. 6-9, 2007.
The population refers to the entire group of interest that the researchers want to study. In this case, the population would be the adult U.S. residents aged 18 and older.
The sample, on the other hand, is a smaller subset of the population that is selected to participate in the survey. The sample allows researchers to gather data from a representative group and make inferences about the population as a whole.
Considering this information, the correct answer would be option B: The population is adult U.S. residents, and the sample is the 1,027 adults who were interviewed.
