Pollsters regularly conduct opinion polls to determine the popularity rating of the current president. Suppose a poll is to be conducted tomorrow in which 2.500 individuals will be asked whether the president rs doing a good or bad job. The 2,500 individuals will be selected by random-digit telephone dialing and asked the question over the phone. Complete parts a through I a. What is the relevant population? A. All people who respond that the president is doing a good job B. All people who do not respond to the survey C. The 2,500 individuals surveyed D. All people in the country

## Step 1<br />The problem is asking us to identify the relevant population for an opinion poll about the current president's performance. The relevant population is the group of individuals from which the sample is drawn for a study or survey. <br /><br />## Step 2<br />Option A is not the correct answer because it only includes people who respond that the president is doing a good job. This is a subset of the population and does not represent all the people who could potentially respond to the survey.<br /><br />## Step 3<br />Option B is also not the correct answer because it includes people who do not respond to the survey. These individuals are not part of the sample and their opinions are not being considered in the survey.<br /><br />## Step 4<br />Option C is not the correct answer because it only includes the 2,500 individuals surveyed. This is the sample, not the population.<br /><br />## Step 5<br />Option D is the correct answer because it includes all people in the country. This is the population from which the sample is drawn. The survey is being conducted to gather opinions from the population, and the sample is a subset of this population.
