A political pollster is conducting an analysis of sample results in order to make predictions on election night. Assuming a two-candidate election, if a specific candidate receives at least

5454%

of the vote in the sample, that candidate will be forecast as the winner of the election. You select a random sample of

100100

voters. Complete parts (a) through (d).
