Shelby · Answer 1

The total number of samples is

11 + 20 + 11 + 27 + 23 + 28 + 11 + 3 + 9 + 1 + 4 + 2

42 + 78 + 23 + 7

150

The percentage of voters based on the survey that voted for Candidate 2 is

78/150 = 52%

The expected number of voters is

8400 x 75% = 6300 voters

The estimated number of voters voting for candidate 2 is

6300 x 52% = 3276 votes
