Answer:918
Step-by-step explanation:
Number of registered voters in the political candidate’s electorate= 115934
Number of voters responded to the survey= 1859
 Percent voters stating they would vote for that candidate= 49.4% 
Value of sample size = 
Percent of voters/100 *1859
(49.4/100 )*1859
= 918.346
≈918
Hence,the value of the sample size is 918
