b. The sampling method is biased. It will almost certainly overestimate the level of support among all Lafayette residents.

c. This is a census, because all fans had a chance to be asked. It gives very accurate results.

d. This is a random sample. It gives very accurate results.

e. The sampling method is biased. It will almost certainly underestimate the level of support among all Lafayette residents.

Answer 1

The survey conducted outside the Lafayette Leopards' stadium is a biased sampling method that will likely overestimate the level of support among all Lafayette residents.

Step-by-step explanation:

The survey conducted by the sportswriter outside the Lafayette Leopards' stadium is an example of a sampling method that is biased. It is considered a convenient sample rather than a random sample, as the first 20 people entering the stadium were interviewed.

This type of sampling method will almost certainly result in an overestimation of the level of support among all Lafayette residents, as only those attending the game were included in the survey.
