Answer:

120

Step-by-step explanation:

Remember, always round sample size up, regardless of the decimal part. Answer: To find a 95% CI with a margin of error no more than ±3.5 percentage points, where the true population proportion is around 42%, you must survey at least 764 people. 10×764 = 7640; presumably the electorate is larger than that. So, then 10 × 12 = 120
