On one episode of his show, a radio show host encouraged his listeners to visit his website and vote in a poll about proposed tax increases. Of the 4821 people who vote, 4277 are against the proposed increases. To which of the following populations should the results of this poll be generalized?

a. All people who have ever listened to this show

b. All people who listened to this episode of the show

c. All people who visited the show host's website

d. All people who voted in the poll

e. All people who voted against the proposed increases

A radio show host encouraged his listeners to visit his website and vote in a poll over potential tax rises on one of his shows. 4277 persons out of 4821 voted against the proposed hikes.

The general public is interested in a variety of topics about which they desire to learn more. A sample is a small portion of a larger population.

The sample is observed to be the 4821 persons that voted on the website. People with strong opinions are more likely to participate in a voluntary response sample, hence there will only be data about strong opinions, resulting in consistent overestimation and underestimation of genuine opinions.

As a result, the best solution is (d)

a. All people who have ever listened to this show is not the answer.

b. All people who listened to this episode of the show is not the answer.

c. All people who visited the show host's website is not the answer.

e. All people who voted against the proposed increases is not the answer.
