Shortly after the introduction of a new currency to a certain country, newspapers around the world published articles claiming the coin was biased. The stories were based on reports that someone had spun the coin 290 times and gotten 165 heads - that's about \( 57 \% \) heads. Do you think this is evidence that spinning the coin is unfair? Explain.
