The football coach wants to estimate the percentage of people from the town who will attend the next game. to estimate this percentage, he plans to conduct a survey of a sample of people. which group should he survey in order to get the best estimate? a: all people that attended the last football game b: a randomly selected group of people from the town c: a randomly selected group of people who are on sports teams d: all people who have a friend on the football team

B: a randomly selected group of people from the town

Step-by-step explanation:

Choosing people that attended the last football game will bias the results.  If they attended the last game, the likelihood of them attending the next game is higher.

Choosing people who are on sports teams will also bias the result.  Sports fans are more likely to attend a football game than non-sports fans.

Choosing people with friends on the football team will bias the results.  Friends of players are more likely to attend games than others.

Choosing random people from town will give results that are less likely to be biased.
