Answer:
a. We believe that the true proportion of county residents who want the law changed is between 26% and 34%
Step-by-step explanation:
The sample point estimate, at a 95% percent confidence level, gives the political action committee an estimate of the true proportion of residents who support a change to the county leash law within a margin of error.
If the point estimate was 30% with a margin of error of 4%, there's a 95% chance that the true proportion is between 26% and 34%.
Therefore, the correct answer is: a. We believe that the true proportion of county residents who want the law changed is between 26% and 34%
