A newspaper article about the results of a poll states:

"In theory, in 98 cases out of 100, the results of such a poll should differ by no more than 5 percentage points in either direction from what would have been obtained by interviewing all voters in the United States."

Find the sample size suggested by this statement. Show your answer as an integer!

(HINT: Based on the above statement, margin of error is 5%; note that sample proportion is not mentioned here.)
