Step-by-step explanation:

A) The poll is inconclusive because the number of people who will vote in favor is 52% it means 48% will vote against. And if there is a 3% error then the election is inconclusive because 52-3 = 49% so it would have been 49% voting in favor of the 3%error had gone against them while the others will have 48+3 = 51% of the vote for themselves. Due to this the election is inconclusive.

B) the confidence level is 97%
