A certain region would like to estimate the proportion of voters who intend to participate in upcoming elections. A pilot sample of 50 voters found that 29 of them intended to vote in the election. Determine the additional number of voters that need to be sampled to construct a 92% interval with a margin of error equal to 0.04 to estimate the proportion. The region should sample additional voters. (Round up to the nearest integer.)
