Cliff wants to determine whether people prefer red apples or green apples. In order to obtain good results, he decides to conduc
t this survey at a car festival. Out of the 5000 people who attended the festival, Cliff surveys 10 attendees randomly. The survey reads, "Which do you prefer, red apples or green apples" Seven of ten people surveyed answer that they prefer red apples. From his survey, Cliff concludes that most people prefer red apples. Cliff's results may not be reliable because of _____________ problems with his study?
The problem with Cliff's survey is that his sample size is too small. 10 out of 5,000 people represent only 0.2%of the population that attended the festival, which is too small of a sample for a reliable study.
Furthermore, since Cliff's question was to determine whether people, in general, prefer red apples or green apples, the sampling of only people who attended the festival might no be adequate.
