I want to know if my coin lands on heads more often than it lands on tails. I decide to test the coin. I flip the coin 100 times, and it lands on "heads" a total of 53 times (53/100 = 0.53 = 53%). Is this strong evidence that the die is not fair?

• Yes, since it didn't roll 50 heads out of 100 = 50% heads, this is strong evidence that the coin is not fair.
• No, since getting 53 heads out of 100 is an expected, usual result to get if the coin is fair, we conclude that it is plausible that the coin is fair.
• Yes, since getting 53 heads out of 100 is unusual, we conclude that we have strong evidence that the coin is not fair.
