votes she could receive?

Answer 1

The lowest percentage of votes she could receive is 40%

Explanation:

43% of students say they will vote for Alessandra, with a margin of error of 3%.

This means that between 43% - 3% = 40% and 43% + 3% = 46% of the students will vote for Alessandra.

This means that the lowest percentage of votes she could receive is 40% and the highest is 46%.
