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 goal is to survey adults attending games across the 18-team league to assess views on sportsmanship. However, the sample only includes adults from one game, supporting just two of the 18 teams. This sample is not representative of the entire population of adults attending games for all league teams, creating biased sampling that undermines the result validity.

Answer:

invalid because of biased sampling
