To find the percentage of the total polled residents who would vote for Candidate A, we need to first calculate the total number of residents who prefer Candidate A from both samples.
From Sample 1, Candidate A received 346 votes. From Sample 2, Candidate A received 248 votes.
Now let's calculate the total votes for Candidate A:
\[ \text{Total votes for Candidate A} = 346 + 248 = 594 \]
Next, we need to find the total number of residents polled, which is the sum of both samples:
\[ \text{Total residents polled} = 500 + 500 = 1000 \]
Now, we can calculate the percentage of the total residents who would vote for Candidate A:
\[ \text{Percentage for Candidate A} = \left( \frac{594}{1000} \right) \times 100 \]
\[ \text{Percentage for Candidate A} = 59.4 \]
Thus, the percentage of the total polled residents who would vote for Candidate A is:
59.4%
