A political analyst conducted two random surveys to estimate the approval rating of a public official. The results are shown in the table:
| Survey | Approval Rating | Margin of Error |
|---|---|---|
| X | 30% | 5% |
| Y | 60% | 2% |
Both surveys used the same polling method and sampled from the same population. Which is the most likely reason that the margin of error for survey X is greater than that for survey Y?
Survey X asked more questions.
Survey X had a higher approval rating.
Survey X sampled from a narrower demographic.
Survey X had a smaller sample size.
