a political party sends a mail survey to 1500 randomly selected registered voters in a community. the survey asks respondents to give an opinion about the job performance of the current president. of the 1500 surveys sent out, 480 did return, and the rest did not return, and only 120 show that the respondent is satisfied with the presidents job performance.
the sample is:
o a. the 1500 randomly selected voters who received the questionnaire.
o b. the 480 voters who returned the surveys.
o c. the 120 voters surveyed who are satisfied with the presidents job performance.
o none of the above

Explanation:

In sampling, the sample consists of the individuals who actually respond to the survey. Here, 480 voters returned the surveys, but only 120 of those respondents showed a particular opinion (satisfaction in this case). However, the sample is defined by those who returned the surveys (as they are the ones providing data). The 1500 selected voters are the population from which the sample (those who returned) is drawn. The 120 satisfied voters are a subset of the sample (those who returned).

Answer:

B. the 480 voters who returned the surveys.
