A political action committee wanted to estimate the proportion of county residents who support a change to the county leash law. They took a random sample of 600 county residents and found that the proportion who wanted to change the law was 34% with a margin of error of +/- 4% (with 95% confidence). This implies:
Choose one answer.
If we take many other samples from this population 95% of them will have a sample proportion that is between 30% and 38%.
We can not conclude anything about the population parameter since this is only a sample.
We are 95% confident that the true proportion of county residents who want the law changed is between 30% and 38%.
There is a 95% chance that the true parameter is 34%.
If we took another sample of 600 residents the sample proportion would definitely be between 30% and 38%.
