Acertain region would like to estimate the proportion of voters who intend to participate in upcoming elections. a pilot sample of 25 voters found that 21 of them intended to vote in the election. determine the additional number of voters that need to be sampled to construct a 94% interval with a margin of error equal to 0.04 to estimate the proportion. the region should sample additional voters.

272

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.
