Some news organizations maintain a database of customers who have volunteered to share their opinions on a variety of issues. Suppose that one of these databases includes 9000 registered voters in California. To measure the amount of support for a controversial ballot issue, 1000 registered voters in California are randomly selected from the database and asked their opinion. Which of the following is the largest population to which the results of this survey should be generalized?

a. The 1000 people in the sample
b. The 9000 registered voters from California in the database -> this is the right answer
c. All registered voters in California
d. All California residents
e. All registered voters in the United States

Sagot :

Using sampling concepts, it is found that the correct option is:

b. The 9000 registered voters from California in the database.

Example of sampling, involving sample and population:

I survey 1000 randomly selected residents of New York State, asking if they are Buffalo Bills fans or not.

  • The sample is the 1000 residents surveyed.
  • The population is all New York State residents, as it is the pool with all available options to be sampled.

In this problem, 1000 registered voters in California are randomly selected from the database and asked their opinion, hence:

  • The 1000 voters are the sample.
  • The pool with all available options to be sampled is the 9000 registered voters in California from the database, hence, it is the population, and option b is correct.
