Question

a towns athletic league contains 18 baseball teams. the board members of the league want to survey adults attending games to determine if they believe the athletes are showing good sportsmanship. the board members attended one game and surveyed an equal number of adults supporting each of the two teams. which best explains the validity of the results? invalid because of biased sampling invalid because the sampled adults are not part of the population valid because an equal number of adults supporting both teams were surveyed valid because adults are the target population

Explanation:

The survey only sampled adults from one game and from two - specific teams. This is a biased sample as it doesn't represent all adults attending games across all 18 teams. A proper sample should be more randomly selected from all games and all teams to accurately determine if athletes are showing good sportsmanship.

Answer:

invalid because of biased sampling
