1. The problem statement, all variables and given/known data A Gallup Poll of 1002 adults in October 2002 found that 25% of the respondents said that their household had experienced a crime in the past year. Among respondents aged 18-29 years, 43% had been victims of a crime. Gallup says, “For results based on the total sample of national adults, one can say with 95% confidence that the margin of sampling error is +/- 3 percentage points.” Is the margin of error for adults aged 18-29 smaller than, larger than, or the same as +/- 3 percentage points? 2. Relevant equations 3. The attempt at a solution Well, I think because of the smaller sample size, the margin of error would be larger because it is less precise. Yet, this sample size comes from a larger sample size with a given confidence interval width, so I am not sure.
