To find the percentage of the total polled residents who would vote for Candidate A, we first need to sum the total votes for Candidate A from both samples and then find the percentage out of the total number of residents polled.
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 find the total number of residents polled. Since each sample had 500 residents, the total number of residents polled is:
\[ \text{Total residents polled} = 500 + 500 = 1000 \]
Now, we can calculate the percentage of residents who would vote for Candidate A:
\[ \text{Percentage for Candidate A} = \left( \frac{\text{Total votes for Candidate A}}{\text{Total residents polled}} \right) \times 100 \]
\[ \text{Percentage for Candidate A} = \left( \frac{594}{1000} \right) \times 100 = 59.4 \]
So, the percentage of the total polled residents who would vote for Candidate A is 59.4.
