A study of 500 people who regularly attend a gym found that 95% of them say they value physical fitness. From this, a researcher concluded that nearly everyone in the country values physical fitness.
Which of the following best identifies the flaw in the researcher's reasoning?
- It overlooks the fact that fully 5% of the surveyed gym-goers did not actually value physical fitness.
- The sample of 500 gym-goers is far too small to support any reliable statistical conclusion at all.
- It draws a nationwide conclusion from a sample that is not representative of the general population.
- It assumes that joining a gym is the single, exclusive path to physical fitness for anyone.
- It relies on self-reported personal attitudes rather than on any objective, measured indicators of fitness.
