Determine whether each question is biased. explain your answer.
a beverage company conducts a survey in the lobby of a health club to determine people's favorite beverage.

A biased question is a question where you cannot expect a fair reply from the respondents. The people reply in a specific way and its mostly inclined towards one aspect or one direction of the survey.

Now the question is : A beverage company conducts a survey in the lobby of a health club to determine people's favorite beverage.

This question is definitely biased as first its conducted in a lobby where there will be few people and mostly they will be employees of the health club. They all an answer the same way.

Secondly, the survey is conducted in a health club and people who visit such clubs usually do not prefer sodas or beverages.

Rather this survey would have conducted with few hundred people from both groups - the healthy preference and non healthy preference. Then it would have been a fair survey.
