You are the official coin tester for the United States Mint. It is your job to test suspicious coins to make sure the chances of coming up heads or tails on a flip is 50/50. You have tested 1 suspicious coin today and got 9 heads out of 10 flips. With a fair coin, the probability of getting 9 or more heads in 10 flips is just over 1%.

• Is this a statistically significant difference from 50/50?
