Six people have declared their intentions to run for a county commission seat in the next general election. A political poll is conducted three-quarters of the way into the campaign to determine if there are any clear preferences on the part of the voters. One thousand twenty randomly-selected voters were asked to indicate their choice. The responses are presented in the table. (Use the Ch-square method.)

Candidate Number of responses
A 180
B 240
C 200
D 130
E 125
F 145

Test the appropriate hypothesis to determine if there is a preference among the candidates. (Let the significance level = 0.05)
