A candidate must gather at least
8,000 valid signatures on a petition before the deadline in order to run in an
election. One candidate turns in 10,000 signatures right before the deadline,
but its always expected that some percentage of them are invalid. Election
officials take a random sample of 100 signatures and thoroughly investigate
them to find that 84% are valid. Is this statistically significant evidence
that the candidate has enough valid signatures overall? Explain.
