A video game company surveys a random sample of 225 of its best customer
and finds that the average gamer spends $406 a year on games, with a
standard deviation of $26.
Another company is also interested in the amount game consumers spend,
and surveys a random sample of 250 gamers, over all interest levels, and
finds that the average gamer spends $250 a year on games, with a standard
deviation of $15.
Why is the second survey more believable than the first?
