1. Using random digit dialing, researchers call 800 people and ask what obstacles keep them from exercising.
what sampling is used and what bias is present?

The survey of 500 spectators is a sample because it is a subset, or part, of the population of 42,000 spectators at the stadium
is a count or measure of an entire population & provides complete information
numerical measurements or counts - Ex: heights of hot air balloons
Simple random sampling is used, since each number has an equal chance of being dialed, so all samples of 800 phone numbers have an equal chance of being selected.

Bias
-Individuals may refuse to participate in the sample. This may make the sample less representative of the population.
-Individuals may not be available when the researchers are calling. Those individuals that are available may not be representative of the population
-Telephone sampling only includes people who have telephones. People who own telephones may be older or wealthier on average, and may not be representative of the entire population.
