SAT Question 9ee22c16: Inference From Sample Statistics And Margin Of Error answer and explanation with Desmos solution

According to the table, of $400$ voters randomly sampled, the total number of men and women who plan to vote for Candidate A is $202+34=236$. The best estimate of the total number of voters in the town who plan to vote for Candidate A is the fraction of voters in the sample who plan to vote for Candidate A, $\frac{236}{400}$, multiplied by the total voter population of $6,000$. Therefore, the answer is $\left(\frac{236}{400}\right)\times 6,000=3,540$.
