A pollster wishes to estimate the proportion of United States voters who favor capital punishment. How large a sample is needed in order to be 9898% confident that the sample proportion will not differ from the true proportion by more than 55%?

Sample size, n = 543

Step-by-step explanation:

We are given the following in the question:

Margin of error = 5%

Confidence interval:

Margin of error =

Since no particular proportion is given, we take

Putting values, we get,

Thus, the sample size must be 543 so the sample proportion is will not differ by 5%

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
