Step-by-step explanation:

Given : A pilot sample of 25 voters found that 21 of them intended to vote in the election.

i.e.

and the voters sampled = 25

Significance level :

Critical value :

Margin of error: E = 0.04

The formula to find the sample size is given by :-

Then, the additional voters need to be sample =

Hence, the region should sample 272 additional voters.
