Answer:
The margin of of error for a 95% confidence interval for the population mean is of 1.39 years.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
That is z with a pvalue of , so Z = 1.96.
The margin of error is:
In which is the standard deviation of the population and n is the size of the sample.
Population standard deviation of 3 years
This means that
Sample of 18 voters
This means that
Margin of error:
The margin of of error for a 95% confidence interval for the population mean is of 1.39 years.
