Jack is running for city mayor. He stops the first 10 people on the street and asks them what their biggest concern for the city
is. Six of the people say higher taxes are their biggest concern. Jack concludes that most people in the town think higher taxes are the biggest concern. Jack's conclusion is A) valid. Jack asked enough people.
B) invalid. Jack did not ask enough people.
C) incorrect. Six of ten people is not a majority.
D) bias. Jack does not want to raise taxes and is looking for support
Jack's conclusion is B. INVALID. JACK DID NOT ASK ENOUGH PEOPLE.
A city has a population of millions and 10 people is not even a relevant sample of the population. Thus, the conclusion he has drawn based from his interview is insufficient.
