Step-by-step explanation:
Hello!
A city council member wanted to know how her constituents felt about a planned rezoning. She randomly selected 75 names from the city phone directory and conducted a phone survey.
Identify the population and sample in this setting.
The population of interest is confirmed by all the individuals or experimental units that the researcher wants to study. The sample is normally a portion of the population randomly selected and representative of it. Since in most cases it is impossible to study the whole population the sample is taken. Then after the experiment is conducted, the conclusions reached are extrapolated to the whole population.
Normally is easier to identify the sample first and then the population, in this example, the sample is "75 names from the city phone directory" then the population will be "people registered in the city phone directory"
The correct option is the first one.
> The population is everyone listed in the city phone directory; the sample is the 75 people selected. CORRECT
> The population is residents of the city; the sample is the registered voters in the city. INCORRECT
> The population is registered voters in the city; the sample is everyone listed in the city phone directory. INCORRECT
I hope this helps!
The 75 individuals selected constitute the sample.
Randomly selected:
The probability that two randomly selected subsets of the set {1, 2, 3, 4, 5} have exactly two elements in their intersection.
In sample surveys, the population is the universal set of units, from which we choose the same. In this example, the member picked up a sample from the phone directory. Thus, the population is the set of all those residents who are registered on the telephone directory. From there, a sample of size 75 is picked.
Thus, the 75 individuals selected constitute the sample.
